Colorization is the process of replacing a scalar value stored at each pixel of a grayscale
image or film by a vector in a multidimensional color space. Mapping between scalar and …

This work presents a simple process for gray image colorization, using a colored image
which is similar to this gray scale image but not the colorized version of the gray image. This …

In biometric identification, fingerprints are most widely used. Fingerprint identification has
become time consuming because of growing size of fingerprint databases. Fingerprint …

The paper presents an innovative technique for colorization of grayscale images. Here the
colors from some source color image are picked up and sprayed into the to be colored …

Vector Quantization (VQ) is one of the Lossy Image Compression Techniques. Vector
Quantization is performed in three phases: 1. CodeBook Generation, 2. Image Encoding and …

Fingerprints are the most widely used form of biometric identification. Fingerprint
Classification is done to associate a given fingerprint to one of the existing classes …

The storage of colour information in a greyscale image is not a new idea. Various
techniques have been proposed using different colour spaces including the standard RGB …

Colorization is adding colors to black and white images. Colorization attracts the interest of
researchers as it serves wide are of applications such as web technology and medical …

Colorization is a practice of adding colors to gray scale images and videos. This research
