We guide research scholars in choosing novel digital image processing project topics. What is meant by digital image processing? Digital Image Processing is a method of handling images to get different insights into the digital image. It has a set of technologies to analyze the image in multiple aspects for better human / machine image interpretation. To be clearer, it is used to improve the actual quality of the image or to abstract the essential features from the entire picture is achieved through digital image processing projects.

This page is about the new upcoming Digital Image Processing Project Topics for scholars who wish to create a masterpiece in their research career!!!

Generally, the digital image is represented in the form of pixels which are arranged in array format. The dimension of the rectangular array gives the size of the image (MxN), where M denotes the column and N denotes the row. Further, x and y coordinates are used to signify the single-pixel position of an image. At the same time, the x value increases from left to right, and the y value increases from top to bottom in the coordinate representation of the image. When you get into the DIP research field, you need to know the following key terminologies.

Digital Image Processing Techniques

• Low pass filters (mean, weighted mean, median, mode)
  • In order to smooth the image, substitutes neighbor median / common value in the place of the actual pixel value. Whereas it is performed in the case of weak edge sharpness and blur image effect.
• Geometric operation
  • Eliminate the distortion in an image by scaling, wrapping, translation, and rotation process
• Color Enhancement/Transformation
  • Differentiate the in-depth image content to figure out the original hidden data or to convert the color image into a gray-scale image
• Segmentation
  • Breaking up of image into multiple forms based on certain constraints. For instance: foreground, background
• Contrast enhancement         
  • Enhance the image display through pixel-based threshold operation 
• Averaging
  • Reduce the noise in an image by the average of diverse quality multiple images 
• High pass filters
  • Sharpening the image by improving the pixel value in the edge
