Abstract |
|
|
| In this paper a novel color image compression technique for efficient storage and delivery of data is proposed. The proposed
compression technique started by RGB to YCbCr color transformation process. Secondly, the canny edge detection is used to classify
the blocks into edge and non-edge block. Each color component Y, Cb, and Cr compressed by discrete cosine transform (DCT) process,
quantizing and coding step by step using adaptive arithmetic coding. Our technique is concerned with the compression ratio, bits per
pixel and peak signal to noise ratio, and produc better results than JPEG and more recent published schemes (like, CBDCT-CABS and
MHC). The provided experimental results illustrate the proposed technique is efficient and feasible in terms of compression ratio, bits
per pixel and peak signal to noise ratio. |
