Glcm matlab code 6036 Correlation: 0. This matrix is largely diagonal, which means that the pixels' intensities are highly correlated. The features extracted from the GLCM above are as follows: Contrast: 518. Code #1: Display histogram of an image using MATLAB library function. Apr 28, 2025 · An image histogram is chart representation of the distribution of intensities in an Indexed image or grayscale image. The displayed GLCM corresponds to an offset "one pixel to the right". Continue Reading: Texture Measures from GLCM - MATLAB CODE Feb 15, 2024 · Image and its GLCM with 255 levels, 50 pixel offset along Vertical direction (90 degree) Feature extraction plays a pivotal role in image processing and computer vision tasks. A GLCM can reveal certain properties about the spatial distribution of the gray levels in a texture image. 9335 Energy: 0. 0015 Homogeneity: 0. 3772. You can also derive several statistical measures from a GLCM. MATLAB % Read an Image in MATLAB Environment img=i The maximum value of the pixel in the matrix A is 8 so the quantization level is fixed to 8. Matlab code and a PDF that implements the GLCM functions necessary for the Digital Image Analysis class INF9305 at UiO. It shows how many times each intensity value in image occurs. For instance, in the example given above, the pixel 2 and its neighbor 3 occurs 3 times in matrix A and it is updated in the GLCM matrix at the position (2,3) as 3. Element (1, 2) in the GLCM contains the value 2 because there are two instances where two horizontally adjacent pixels have the values 1 and 2 . For example, if most of the entries in a GLCM are concentrated along the diagonal, then the texture is coarse with respect to the specified offset. In the GLCM, element (1, 1) contains the value 1 because there is only one instance in the input image where two horizontally adjacent pixels have the values 1 and 1, respectively.
