RGB color model

Image zoomin in matlab

The following Matlab project contains the source code and Matlab examples used for image zoomin. zoom in gray images from size n_by_m to 2n-1_by_2m-1, using semple algorithm with presentation for the algorithm, and examples for how to zoom the RGB images and how to convirt color system from RGB to YUV and visa versa then test the correlation between zomed image and original one.

Rgb image decomposition in matlab

The following Matlab project contains the source code and Matlab examples used for rgb image decomposition. Function imColorSep takes a single input argument, an M x N x 3 array representing a full color RGB image, and generates a figure window containing four images: the original full color image, and the three individual monochromatic images representing the red, green, and blue components of the original image.

Rgb() converts a color index or name into an rgb triple with real-valued components in [0,1]. in matlab

The following Matlab project contains the source code and Matlab examples used for rgb() converts a color index or name into an rgb triple with real-valued components in [0,1]. . OVERVIEW The Matlab function RGB() converts a color index (whole number from 1-21), English name of a color (string), or RGB triple with whole number components in {0, 1, .

Color systems in matlab

The following Matlab project contains the source code and Matlab examples used for color systems. This code converts regular RGB images into five other color systems--RBG,GRB,GBR,BRG,BGR. Changing the color systems gives a different experience of how things could look even more beautiful in other colors.

Gray2rgb in matlab

The following Matlab project contains the source code and Matlab examples used for gray2rgb. This just makes a grayscale image, with values ranging from 0 to 255, into a RGB truecolor image with values ranging from 0 to 1 in each of the 3 colors.

Cbimage checkerboard superposition of two images in matlab

The following Matlab project contains the source code and Matlab examples used for cbimage checkerboard superposition of two images. checkerboard image, superimpose two images (grayscale/RGB) with a chess pattern Syntax:   imFinal = cbimage(im1, im2);   imFinal = cbimage(im1, im2, 20); % 20 subdivisions   imFinal = cbimage(im1, im2, [], 10); % lower-intensity pattern got -10 % of max-min Inputs:       im1: grayscale or RGB image of any size (NxNx1 or NxNx3)       im2: second grayscale or RGB image with the size of im1

Transform a gray image to pseudo color image in matlab

The following Matlab project contains the source code and Matlab examples used for transform a gray image to pseudo color image. function rgb = ImGray2Pseudocolor(gim, map, n) % IMGRAY2PSEUDOCOLOR transform a gray image to pseudocolor image % GIM is the input gray image data % MAP is the colormap already defined in MATLAB, for example: % 'Jet','HSV','Hot','Cool','Spring','Summer','Autumn','Winter','Gray', % 'Bone','Copper','Pink','Lines' % N specifies the size of the colormap % rgb is the output COLOR image data %.

Miscellaneous tools for image processing in matlab

The following Matlab project contains the source code and Matlab examples used for miscellaneous tools for image processing. eachchannel  allows us to apply function for each channel imgrad  calculates horizontal and vertical gradients impsnr  evaluates the psnr and the rmse beween images imreadind  reads image file from file even if the image file is index color, imreadind can read image data as well as rgb image data   rgb2ycc  transfers color space from rgb to ycc ycc2rgb  transfers color space from ycc to rgb .
