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

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}

Free space optical communications is a line-of-sight (LOS) technology that transmits a modulated beam of visible or infrared light through the atmosphere for broadband communications. In a manner similar to fiber optical communications, free space optics uses a light emitting diode (LED) or laser (light amplification by stimulated emission of radiation) point source for data transmission. However, in free space optics, an energy beam is collimated and transmitted through space rather than being guided through an optical cable. These beams of li ....etc

We have done a detailed analysis of the visual properties of the HSV (Hue, Saturation and Intensity Value) color space and Human visual system. Using the results of these analyses, we determine relative importance of hue and intensity based on the saturation of an image pixel with respect to rod and cone cells excitation of retina. We effectively apply this method to the generation of a color histogram and use it for content-based image retrieval applications. A web-based system has been developed for demonstrating our work ....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
