  Grayscale images are similar to indexed images in that each uses an m-by-3 RGB colormap, but you normally do not specify a colormap for a grayscale image. MATLAB displays grayscale images by using a grayscale system colormap (where R=G=B).

  Figure 1 can be stored in MATLAB as a variable that contains an array of numbers, with each number referring to the gray scale value for each pixel of the image. A sub-sample of the complete Figure 1 file is shown in Table 1; this sub-sample shows the gray scale values for the square superimposed on Figure 1 and magnified by itself in Figure 2.

• [DOC File]JPEG Image Compression Implemented in Matlab

  https://info.5y1.org/grayscale-image-matlab_1_75daa7.html

  In this project I attempted to implement basic JPEG compression using only basic Matlab functions. This included going from a basic grayscale bitmap image all the way to a fully encoded file readable by standard image readers. I will show that I have implemented the majority of the project, including much of the final binary coding.

  Load the mushroom image from the course website. In MATLAB you can use the command “imread()” to read a file. If you want help to understand how this command works, type help imread in the command window. This image is a grayscale image but saved as a .jpg.

  in every image. Convert the color image P1 into grayscale image with the following command: bw = rgb2gray(P1); Compute the histogram of the grayscale image. As we will not be considering the black pixels surrounding the retina, only consider the pixel values ranging from 51 to 255.

  Image histograms provide a means to visualize the distribution of grayscale intensity values in the entire image. They are useful for estimating background values, determining thresholds, and for visualizing the effect of contrast adjustments on the image (next section). The matlab function to visualize image histograms is imhist

  Image frame is loaded from an external jpeg file and Matlab converts it to RGB 3-dimentional matrix. In order to reduce the dataset to more manageable size, each image has been reduced in size by 50% and subsequently converted to grayscale. The two-dimensional grayscale matrix is then reshaped into 8x8 blocks using the im2col Matlab function.
