Literature Review Title: Image Compression: A Survey 
Chapter Title:  S-TREE AND SHADING APPROACH 
1. Abstract of Cited Paper (BIB001):  Distasi et al. (see ibid., vol.45, p.1095-1100, 1997), presented a storage-saving image compression method called the B-tree triangular coding (BTTC) method. Based on the modified S-tree data structure and the Gouraud shading method, this paper presents an improved image compression method railed the S-tree compression (STC) method. Experimental results illustrate that the bit rates and the image quality of the proposed STC method are quite competitive with the BTTC method, Due to the simple geometrical decomposition in the STC method, the ratio of the execution time or the proposed method over the BTTC method is less than 1/2.

Literature Review:
Novel method is presented for compression of gray image Rate of bits and the quality of image shows that STC method is reliable then BTCC method. Execution cycle of proposed method is min than half than BTCC. In each block by considering noise and increasing the execution time image's quality is also preserved in a satisfactory ways of proposed shade tree method can get improvement at very high rate BIB002 BIB001 .
