我们将使用Python编程语言实现一个简单的图像压缩算法,该算法基于离散余弦变换(DCT)和量化。下面是我们的代码示例: importnumpyasnpimportcv2defcompress_image(image,quality):img=cv2.imread(image,cv2.IMREAD_GRAYSCALE)dct=cv2.dct(np.float32(img)/255.0)quantization_matrix=np.array([[16,11,10,16,24,40,5...

定义框架矩阵为0,维度为4x4,这个大小是从上面的量化级别矩阵中得到的, python Quantization level = count(gray tone) 所以对于灰度 0-3,我们得到量化级别 = 4,这样我们必须创建一个大小为 4x4 的框架矩阵 0000000000000000 框架矩阵中的每个位置都是3x3输入矩阵中像素值的组合。 考虑到灰度在 0 -255 之间,一个 ...
Python Lossy PNG compressor for RGBA PNGs. Has two modes: lossy averaging filter (blurizer) that denoises the image and optimal posterization using Median Cut quantization to reduce number of unique colors in the image with minimal visual distortion ...
