This Function intra_cons does the function of Intra Prediction on a block. If Block Size is 4x4, then there are 9 modes defined and if Block size is either 8x8 or 16x16, then there are 4 modes defined by H.264 std. All the modes are implemented separately below, as functions. Mode selection is based on which mode results in smaller SAD (Sum of Absolute Difference).
I and J are pixel numbers, N is the block size
This function is used for H.264 video format encoding and decoding
Example:
[intra_image,intra_mode,blk_size]=intra_cons(image,1,1,8)
