color co occurrence matrix matlab code

A co-occurrence matrix or co-occurrence distribution (less often co ccurrence matrix or co ccurrence distribution) is a matrix that is defined over an image to be the distribution of co-occurring values at a given offset. Mathematically, a co-occurrence matrix C is defined over an n m image I, parameterized by an offset ( x, y), as:

C_{\Delta x, \Delta y}(i,j)=\sum_{p=1}^n\sum_{q=1}^m\begin{cases} 1, & \text{if }I(p,q)=i\text{ and }I(p+\Delta x,q+\Delta y)=j \\ 0, & \text{otherwise}\end{cases}

deblurring of color images corrupted by impulsive noise matlab code

Abstract

We consider the problem of restoring a multichannel image corrupted by blur and impulsive noise (e.g., salt-and-pepper noise). Using the variational framework, we consider the L1 fidelity term and several possible regularizers. In particular, we use generalizations of the Mumford-Shah (MS) functional to color images and gamma-convergence approximations to unify deblurring and denoising. Experimental comparisons show that the MS stabilizer yields better results with r ....etc

Visual cryptography is a popular solution for image encryption. Using secret sharing concepts, the encryption procedure encrypts a secret image into the so-called shares which are noise-like secure images which can be transmitted or distributed over an untrusted communication channel. Using the properties of the human visual system to force the recognition of a secret message from overlapping shares, the secret image is decrypted without additional computations and any knowledge of cryptography.

Visual cryptographic solutions operate on binar ....etc

cbir color autocorrelogram code in matlab and algorithm

ABSTRACT

Much of the information stored in digital libraries will contain either images or video, which is difficult to search or browse. Automatic methods for searching image collections make wide use of color histograms, because they are robust to large changes in viewpoint, and can be computed trivially. However, color histograms fail to incorporate spatial information, and therefore tend to give poor results. We have developed several methods for combining color information with spa ....etc
