Spacial Prediction of Images

This function spacial_predict does spatial prediction of the input image. It plots the resultant image and the Mean square error if the plot flag is 1. The function outputs the Error of the predicted image(E_spatial) and the predicted image (PS) itself. The input image has to be of the format image(rows,cols) and should not be a 3D image or a RGB image.
Example:
file=('<Path of image file>');
plotflag=1;
im = imread(file); image=im(:,:,1);
[E_spatial,PS]=spatial_predict(image,plot_flag);
