Cochin University introduces Digital Image Processing Papers to orient students with image processing methods by giving them the literature and modules of study. The fundamentals of digital processing begin with the components of visual perception, relation existing between pixels, geometric transformations and transforms like Fourier and DFT. The topics set down the image enhancement procedures like spatial domain method which consist of smoothening and sharpening techniques, image subtraction and image averaging, filtering and grey zone transformation. It also takes into account image restoration by educating the students on the models of degradation and restoration of images where concepts of noise models and inverse filtering become the priority. Also image compression is a technical area that comprises of the coding systems like variable length, bit plane and predictive coding. Then come image fragmentation and depiction based on regions using concepts of thresholding, boundary representation, polygonal approximation and descriptors from simple to Fourier.
