Abstract |
|
Recent research has focused on the new proposed Bayer pattern image compression compared to other methods of structural transformation algorithm. Based on previous work, this paper proposes a new algorithm the Bayer pattern image compression by using adaptive 9/7 wavelet transform and set partitioning in hierarchical trees (SPIHT) and Huffman coding combined. Start with a color filter array (CFA) data convolution of the low pass filter followed by a down-sampling operation after the data is converted from RGB color space into separated luminance and chrominance components of the YCbCr color space. The lastly achieved more data compressed by using new proposed algorithm method for compression. |
