Summary:本发明公开了一种基于JPEG压缩编码的数字病理全切片图像快速分析方法，首先对从远端获取的图像块的JPEG压缩编码进行解码，获得DCT编码矩阵；然后对DCT编码矩阵依次进行空间下采样和频域下采样从而获得全切片图像压缩编码矩阵，最后采用全切片图像压缩编码矩阵构建全切片分析模型，利用构建好的全切片分析模型即可实现数字病理全切片的自动分析。本发明直接利用JPEG压缩图像解码过程的中间结果生成图片压缩编码矩阵，大幅削减了全切片分块特征提取的计算量，提高了分析速度。 The invention discloses a digital pathological full-slice image rapid analysis method based on JPEG compressed coding, and the method comprises the steps: decoding the JPEG compressed coding of an image block obtained from a far end, and obtaining a DCT coding matrix; then sequentially carrying out space down-sampling and frequency domain down-sampling on the DCT coding matrix to obtain a full-slice image compression coding matrix, finally, constructing a full-slice analysis model through the full-slice image compression coding matrix, and achieving automatic analysis of digital pathological full slices through the constructed full-slice analysis model. According to the method, the picture compression coding matrix is generated by directly utilizing the intermediate result of the JPE
