Rgb Image

Draws a circle or ellipse on a RGB image.can be used to insert circles into movies.Includes a little animation demo that demonstrates the use. Platforms: Matlab

Quadtree decomposition of RGB image of size M-by-N-by-3. Three thresholds for red,green and blue components are used. For any R or G or B block if the maximum value of the block elements minus the minimum value of the block elements is greater than its respective threshold then the RGB block is... Platforms: Matlab

SGI plug-in provides SGI image file load & save modules for The GIMP. The plug-in supports GRAY, GRAYA, RGB, and RGBA color modes. Using the SGI Plug-In: The Parameter Settings buttons control how much compression is applied to the image: No Compression stores the image raw or verbatim. RLE... Platforms: *nix

finding co ordinate values of RGB imagas well as the gray level image.... n finding some other relevent information Platforms: Matlab

IMGOUT = RGB_THRESH(TEMPIMG, REDL, etc) takes a RGB image TEMPIMG, and returns a binary mask IMGOUT that consists of the pixels that are greater than or equal to the LOW RGB values AND less than or equal to the HIGH RGB values. Platforms: Matlab

Interleaves the color pages of an MxNx3 color image array into presumably what was the original, 2Mx2N, intensity output of a Bayer image sensor. Useful for capturing a monochromatic image (like actively illuminated IR) with a color sensor (like a cheap color webcam). It does not compensate for... Platforms: Matlab

This tool is used to blur RGB image with help of inbuilt mask and filters, main concept is to blur layer of Red, Blue and Green individually and than merge them again.Very simple but ready to use formula.Kindly leave feedback if you download same. Platforms: Matlab

This code converts an RGB image to a black and white image in C with MEX. I this together for a school project and I couldn't find any good examples of MEX with image processing. One note the code is currently hard coded to handle only UINT8, however it should be trivial to convert that data... Platforms: Matlab

In this program RGB image is converted to L*a*b color space.Green & purple mode of this color space are chosen & then convert them into binary.AND operation is performed on the images so a matrix is obtained having 1 & 0.One(1) indicate the presence of face. Platforms: Matlab

This function takes an RGB image as input and gives the FWHM and 1/e^2 radius of Gaussian-assumed speckles in the horizontal and vertical directions in pixel units.The function is heavily commented for very easy use, and all mathematical steps are explained in the comments. Briefly, the... Platforms: Matlab

It can be used for emphasis coloration, object identification, labeling and edge detection. Requirements: - MATLAB 7.6 or higher - MATLAB's Image Processing Toolbox Platforms: Windows, Mac, *nix, Matlab, BSD Solaris

GUI for improving resolution of lower resolution image using higher resolution image using RGB-to-HSI conversion.Images have to be spatially co-registered.Monochromatic (gray scale) low resolution image is converged to colored image by false color mapping to "hot" color scheme. This RGB image is... Platforms: Matlab

using image processing techniques ,first change the RGB image to gray scale than applying function to calculate the percentage of white color in an image. Platforms: Matlab

this code does gray scale image compressionto use this codes u have to first convert RGB image to grayscale and also its colormap..... Platforms: Matlab

The Image Processing toolbox toolbox is lacking a key feature I need, namely the support of all data types.Quick list of the source included:imhist_thresh.cpp: Generate histogram from data, # of bins based on unique values.imsmarthist_thresh.cpp: equalize data based on... Platforms: Matlab

IDX = OTSU(I,N) segments the image I into N classes by means of Otsu's N-thresholding method. OTSU returns an array IDX containing the cluster indices (from 1 to N) of each point. IDX = OTSU(I) uses two classes (N=2, default value). [IDX,sep] = OTSU(I,N) also returns the value (sep) of the... Platforms: Matlab

This functions gets an image name which should be RGB, load it and create a .png with transparent color where the RGB image is white.If the third parameter is setted the function will color in black the non-transparent areas Platforms: Matlab

This program just tracks all red color objects and draws a bounding box around them. This works on the difference between frames concept. Every frame in the video is returned as an rgb image on which we can do image processing stuff. Platforms: Matlab

Hough transform for circles in any size.returns a list of all circles found(position and radius) in an RGB image.includes function for:drawing a circle on an image.finding the maximum points in a 1d signal. Platforms: Matlab

RANDBLOCK - randomize blocks of a matrixR = RANDBLOCK(M,S) randomizes the matrix M by dividing M into non-overlapping blocks of the size specified by S, and shuffling these blocks. M can be a N-D matrix.The number of elements in S should match the number of dimensions of M, or S can be a scalar... Platforms: Matlab
