Abstract:
This paper presents an image compression technique for DubaiSat-2 based on Discrete Cosine Transform (DCT). Initially, the image is divided into non-overlapping sub-blocks and transformed to a frequency domain using DCT. Then the thresholding technique is applied to eliminate lower energy coefficients. The resultant coefficients are quantized at a user specified bit rates. The proposed method is tested on both gray scale and color images. The performance of the proposed method is analyzed using Peak Signal-to-Noise Ratio (PSNR).
