Convert Image To Matrix in PythonImport Image module from PILLOW library of Python as PIL. Import array module from NUMPY library of Python. These two libraries are for Image extraction from the source file and defining the dimensions of the matrix.
To display a matrix as a scaled indexed image, use the MATLAB image display function imagesc . For example, let's display a small magic square using image and then compare it with a display using imagesc . Magic square displayed using image with grayscale colormap.
I = rgb2gray( RGB ) converts the truecolor image RGB to the grayscale image I . The rgb2gray function converts RGB images to grayscale by eliminating the hue and saturation information while retaining the luminance.
You can treat a matrix or an image as a matrix(or an image) by calling cvGetMat (or cvGetImage).No data will be copied.
If you want to copy the data, use cvCopy.
