INTRODUCTION Obtaining a high-resolution (HR) image from single or multiple low-resolution (LR) images‚ known as “super-resolution” has been a problem. High resolution means high pixel density‚ also referred to as high-definition (HD). An HR image brings out details that would be blocked out in an LR image. More pixels in the same area imply a higher sampling frequency thereby offering more details. Due to the tremendous progress in sensor and chip manufacturing techniques‚ we can now obtain high

However‚ it fails to detect whole relevant pixels of some types of moving objects. Figure 2.3 shows an inaccurate motion detection example for the salient motion detection. Besides‚ it also fails to detect stopped objects in the frame. In order to overcome this problem‚ additional methods need to be adopted. The Gaussian Mixture Model (GMM) is a single extension of the Gaussian model. The single Gaussian models each pixels in a scene with an estimated mean intensity value. However

techniques. Filtering is one of the enhancement techniques which is used to remove unwanted information (noise) from the image. It is also used for image sharpening and smoothening. Some neighborhood operations work with the values of the image pixels in the neighborhood and the corresponding values of a sub image that has the same dimensions as the neighborhood. The sub image is called a “filter”. The aim of this project is to demonstrate the filtering techniques by performing different operations

Depending on the data hidden in the pixels directly or in the coefficients obtained after a suitable transform domain like FFT‚ DFT or DWT leads to spatial domain Steganography and frequency domain Steganography. Some of the commonly used methods of embedding payload in cover image are least Significant Bits (LSB) substitution in which the LSBs of cover image pixel are altered to hide the payload and more data can be hidden in

In Digital image processing‚ the given image is broken down into many pixels and a numerical value is attributed to each of the pixel resulting in an array of numbers. These numbers are analyzed to get the required information from the image. It is used in Optical character recognition‚ Medical imaging analysis‚ Digital photoelasticity‚ Digital image correlation and real time sports analysis. Pre-processing an image refers to applying filters to the image to get a better image in terms of contrast
