- ColorLab: Color Processing Toolbox
pop
COLORLAB is a high-performance color computation and visualization toolbox for MATLAB 5.3 or higher.
COLORLAB is intended to deal with color in general-purpose quantitative colorimetric applications as color image processing and psychophysical experimentation. COLORLAB uses colorimetrically meaningful representations of color and color images (tristimulus values, chromatic coordinates and luminance, or, dominant wavelength, purity and luminance), in any primaries system. COLORLAB relates these colorimetric representations to the usual device-dependent discrete-color representation. A number of interesting color representations are also provided, as CIE uniform color spaces (as L*a*b* and L*u*v*), opponent color representations based on advanced color vision models, and color appearance representations (RLab, LLab, SVF and CIECAMs).

- KeyRes Run Length Matrix
KeyRes Run Length Matrix is an advanced features extraction and image processing software for scientific and industrial imaging applications.
Supported Run Length Functions are: Short Runs Emphasis, Long Runs Emphasis, Gray Level Non-Uniformity, Run Length Non-Uniformity, Run Percentage, Low Gray Level Runs Emphasis, High Gray Level Runs Emphasis, Short Run Low Gray-Level Emphasis, Short Run High Gray-Level Emphasis, Long Run Low Gray-Level Emphasis and Long Run High Gray-Level Emphasis.
This software supports grayscale images stored in RTOG, TIFF, GIF, JPEG, BMP or many other image file formats. Color images are converted into grayscale images in order to extract meaningful features. Algorithms are fast and optimized using sparse matrix notation and compilation in C/C++ language.
You can choose a pixel-based or a block-based scan, select a sliding window size, a gray level value, and start processing. It is possible to select the neighbouring pixels distance and eventually normalize the result within a 0-255 range.
After processing, perform a 3D visualization, define a correlation map and plot the features histogram. Then, export the feature values - or feature images as well - and import into another image processing tool.

- Colorization Using Optimization
In this paper we present a simple colorization method that requires neither precise image segmentation, nor accurate region tracking. Our method is based on a simple premise: neighboring pixels in space-time that have similar intensities should have similar colors. We formalize this premise using a quadratic cost function and obtain an optimization problem that can be solved efficiently using standard techniques. In our approach an artist only needs to annotate the image with a few color scribbles, and the indicated colors are automatically propagated in both space and time to produce a fully colorized image or sequence. We demonstrate that high quality colorizations of stills and movie clips may be obtained from a relatively modest amount of user input.

- Steganography
Although steganography -- the practice of hiding a secret message within an innocuous cover medium -- is hardly new, detecting the presence of hidden messages has become considerably more difficult with the advent of high-resolution digital images as carriers.
We have been developing statistical techniques to detect (but not necessarily decipher) the presence of hidden messages within a digital image. The basic approach works by finding predictable higher-order statistics of "natural" images within a multi-scale decomposition, and then showing that embedded messages alter these statistics.
