基于DCT域JPEG图像压缩算法的研究与设计

Research and design of JPEG image compression algorithm based on DCT domain

随着图像技术的不断发展,JPEG已成为广泛应用的图像压缩标准。设计详细阐述了JPEG压缩编码的具体过程和方法,包括DCT变换、量化、编码、采用小波变换和DCT变换对压缩的图像进行去噪。实验结果表明设计对图像进行了成功压缩且通过SSIM算法可知压缩质量较高,有可行性且效果比较满意。

With the continuous development of image technology, JPEG has become a widely used image compression standard. Thedesign in the paper details the specific process and method of JPEG compression coding, including DCT transform, quantization, coding, de⁃noising the compressed image using wavelet transform and DCT transform. The experimental results show that the design of this paper hassuccessfully compressed the image and the SSIM algorithm shows that the compression quality is high, which is feasible and satisfactory.
