Intra Prediction Re-Construction of Image in a video frame

To perform the Intra prediction reconstruction to get the image of a video frame

This Function Intra_RECONS preforms the Intra Re-Construction, also known as Spatial Prediction, in image "im_recons"'s current block,(i,j) of size N. The function implements all modes. Which ever mode has earlier been selected,That mode's reconstruction is performed. The function returns the reconstructed block
I and J are pixel numbers, N is the block size
This function is used for H.264 video format encoding and decoding

Example:
rim_intra=intra_recons(image,'Mode 1',1,1,8)
