a new intra prediction algorithm for enhancement layer in spatially scalable video coding is proposed. It takes the spatial correlation between adjacent layers into consideration

and makes use of the magnified decoded and reconstructed base layer block for intra prediction in the lack of neighboring predicting samples. Furthermore

two adaptive weight factors (Wv

 Wh) related to the texture characteristic within an image are introduced to improve the coding efficiency of proposed algorithm. Experimental results show that the PSNR value of luminance component has been increased and both coding bit rate and computation complexity are preserved. As a result

it can be used as an efficient intra coding scheme for enhancement layer in spatially scalable video coding.
