Fingerprint Recognition OpenCV Python

Fingerprint recognition is a method to identify the matching of fingerprint features against the existing stored features for a person’s identity verification. Fingerprint features are nothing but graphical features embedded in fingerprint valleys and ridges. These valleys and ridges can be recognized over fingertips surface. Further, it includes minutiae patterns like bifurcation, ridge spots, and ridge ends.  If you are interested to know the significant research information about Fingerprint Recognition Opencv Python projects, then this is the right page to know your required truthful information!!!

All the patterns/features have a key player role in solving issues related to fingerprint verification and identification system. Compare to other biometric features, the fingerprint is well known for its consistency and uniqueness in identification.

In fingerprint recognition, there are two things that are majorly focused on by many scholars while undergoing their research. As well, they are fingerprint identification and fingerprint verification systems. Although these two research areas may look similar, there exist slight differences which are given below, 

Biometric Identification and Verification System

  • Fingerprint Identification System 
    • It is a one-to-many evaluation system 
    • It captures person’s unique identity (i.e., fingerprint) and looks for matching pattern in the whole database
    • If matches, it identifies the owner of the fingerprint
  • Fingerprint Verification System 
    • It is a one-to-one evaluation system 
    • It also senses person’s unique identity (i.e., fingerprint) and verifies the similarity with pre-stored template (same person’s original fingerprint)
    • If matched, then it declares person’s identity is valid 

From the above list, here we have taken fingerprint identification systems. In this, we have mentioned to you the fundamental two assumptions that you are required to make while fingerprint recognition opencv python system development. As well, they are singularity as well as invariance and singularity invariance. These assumptions are nothing but important characteristics of fingerprints that make researchers choose fingerprint biometric systems

How does fingerprint recognition work? 

  • Singularity
    • The features of the fingerprint are unique where distinct persons will not have the same pattern 
  • Invariance and Singularity Invariance
    • The features of a fingerprint will not change throughout life even while growing

Followed by assumption, here we have also given you the basic functionalities involved in finger identification, enrolment, and verification processes. Let’s have a quick look over them in the following list.

Fingerprint Identification Process

  • At first, since the fingerprint
  • Next, extract the features and prepare feature set
  • Then, pre-select and match the features with n number of templates
  • If a match, identify person’s ID and store in database

Fingerprint Enrolment Process 

  • At first, capture the fingerprints 
  • Next, extract the features and prepare feature set
  • Then, create a template and store the data in the database

Fingerprint Verification Process

  • At first, acquire the fingerprint
  • Next, abstract the features and prepare the feature set
  • Then, check whether the feature set match with one template
  • If a match, then claim the particular user ID is true and store in the database

Now, we can see the four different stages of the fingerprint recognition system. This describes the basic operations of fingerprint recognition systems as image collection from sensors, pre-processing collected information, extracting features from pre-processed data, and matching of extracted features.

 Finally, it finds out whether the given person’s fingerprint is valid by matching with the stored template. Our developers will provide keen assistance in every stage of your fingerprint recognition OpenCV Python in an efficient manner. 

Four stages of Fingerprint Recognition System

  • Acquisition of Images from Sensor 
    • It senses the biometric information like a fingerprint for registration and recognition
  • Pre-processing 
    • It eliminates undesirable and noisy data for more clarity on ridge structure 
    • It uses image pre-processing and enhancement approaches 
  • Feature Extraction
    • It collects important features of fingerprints from pre-processed input 
  • Matching 
    • It matches the collected unique features with stored data (template) in the database

Next, we can see the available patterns in fingerprint used for matching the process. As mentioned earlier, fingerprint recognition is basically dependent on patterns associated with it. In simple words, it collects unique patterns of fingerprints and matches them with already stored patterns in a database for a person’s individuality identification and verification purposes. So, pattern extraction and matching processes play a key role in developing a fingerprint recognition system. Actually, there are two types of patterns as basic patterns and minutiae (advanced) features. Let’s see the permanent and reliable patterns of fingerprint in the below classification.

What are the patterns used for fingerprint recognition? 

Basic patterns

In general, there are 3 fundamental and unique patterns/features in fingerprint ridges and they are

  • Loop
  • Whorl
  • Arch

Here, the loop is usually found in many fingerprints. Loop makes ridges enter and exist on the same side of the finger by forming curves. Whorl makes ridges to form a circular shape over the central point. Arch makes ridges to enter one side of finger and exit on another side of the finger by forming an arch in centre of the finger. All these are the general patterns of fingerprint recognition.   

Minutiae features

Beyond the basic patterns, there are other patterns called minutiae which is the smallest unit of the fingerprint. Also, it is a significant feature point for finger recognition. It is of three types as 

  • Dot / Short Ridge
  • Ridge Ending
  • Bifurcation

Dot ridges are very shortest than other ridges. Ridge endings are finishing points of ridges which indicates by name. Bifurcation is pointed where one ridge divides into two different ridges. All these are collectively called minutiae features / patterns in a fingerprint. 

Next, we can see the important fingerprint recognition challenges. Although fingerprint recognition system is providing several benefits in different fields like digital forensics, cybersecurity, etc., it still has a complication in implementing over real-world scenarios. 

From our current research on fingerprint recognition, we found that the following research challenges/issues are looking for the best solution to take existing fingerprint recognition to next-level developments. Our developers are proficient to solve any kind of complex challenges/issues through our smart solutions. As well, we have excellent solutions for below specified research challenges. 

Recent Issues of Fingerprint Recognition 

  • Latent and Partial Impression
    • Incomplete/unclear collection of fingerprints because of small sensor size 
    • In some cases, it also represents recovered fingerprint
  • High-Dimensional Feature Set
    • The set of features extracted from biometric traits have high dimensionality
    • Consequently, it may increase the computation time of feature processing
  • Non-Universality
    • Some biometrics that does not display all incorporated features
    • For instance: Nearly 4% of fingerprint images may have bad ridge patterns 
  • Unordered Feature Set
    • Regularly, biometric data are not with natural characteristics for ordering / arranging 
    • Therefore, indexing is a challenging task in the clustering method
  • Varied Data Sources
    • Usage of dissimilar sensors at different times will create variation in biometric features
    • In short, images sensed from dissimilar sensors may affect the accuracy of the recognition system
  • Inaccurate and Noisy Sensed Data 
    • Undesired physiological / environmental state make a sensor to sense noisy data 
    • Also, it may cause failure in the biometric authentication system 
  • Intra and Inter class variability
    • Intra-class variability 
      • Dissimilar samples for single biometric feature at the varying instance
      • Occur in the time of sensor feature alteration or improper communication with sensors
      • For instance: A person has various expressions which change over time 
    • Inter-class variability
      • Two different people has same biometric values
      • For instance: identical twins 

OpenCV Python for Fingerprint Recognition 

As a matter of fact, OpenCV python work as well-suited software for developing fingerprint recognition system. This software has the competency to capture person’s fingerprint from a fingerprint scanner. Further, it includes all necessary libraries and functions to process collected key features of fingerprint and look for matching patterns from the database. By the by, this pattern matching process is performed either in one-to-one or one-much aspects.

How to implement fingerprint recognition OpenCV Python? 

Now, we can see in what way fingerprint recognition using OpenCV python takes place over biometric authentication. Generally, fingerprints are recognized by unique patterns of fingerprint ridges like whorls, arches, and loops. While authenticating, these patterns are compared with already stored original patterns. Commonly, the fingerprints recognition process is executed in 3 different stages, which are given as follows, 

3 Stages of Fingerprint Recognition  

  • Stage 1 
    • Take the picture of the fingerprint using electronic optical-camera 
    • Resultant should specify ridges of fingerprint in digital black and white photos
  • Stage 2
    • Convert the image into a numerical model for acquiring unique features of fingerprint in the form of serial numbers
    • For instance: loops, distance, arches, etc.
  • Stage 3 
    • Discover the similarities by comparing the recognized numerical model with already stored original numerical model 

Now, we can see the significant techniques used in general fingerprint recognition systems followed by security techniques and feature extraction techniques. In fact, our developers have developed an infinite number of projects in the fingerprint recognition system.
