有损压缩:通过去除人眼不易察觉的图像细节来减小文件大小,如JPEG格式就采用这种方式。 无损压缩:通过优化数据存储方式来减小文件大小,不会损失图像质量,如PNG格式采用这种方式。 尺寸调整:通过减少图片的像素数量来减小文件大小。 元数据移除:删除图片中的额外信息,如EXIF数据等。压缩模式说明缩小优先:适用于需要大幅减小文件大小的场景 压缩质量设置为

An image wavelet converting unit decomposes an original image into wavelet coefficient blocks according to JPEG2000 algorithm to be transmitted to a memorizer; a wavelet coefficient reading and controlling unit reads the coefficient blocks from the memorizer according to a preset scanning order to be ...
*OS Windows Server 2016, CUDA-10.2 (64-bit). Timings include GPU computations only, single frame image processing at just one GPU for 24-bit images. JPEG encoding with compression ratio ~10:1 and subsampling 4:2:0. Demosaic algorithm is DFPD. Resize algorithm is Lanczos (2x downscaling)....
This example shows how to reduce JPEG compression artifacts in an image using a denoising convolutional neural network (DnCNN).
