Abstract

The invention relates to an annotation data compression method, an electronic device and a storage medium, and the method comprises the steps: obtaining annotation data of an original image, the annotation data comprising a pixel position of an annotation label and an annotation label value, and the pixel position of the annotation label comprising a first dimension value and a second dimension value; and serving the annotation label value and the first dimension value as indexes, encoding the annotation data, and obtaining a multi-level encoding dictionary, wherein the second dimension value comprises one or more continuous intervals, and the encoding value of the second dimension value is represented by the starting value and the stopping value of each continuous interval. According to the invention, the problem of low compression and transmission processing efficiency of the annotation data in the prior art is solved, and the compression and transmission processing efficiency of the annotation data is improved.

Description

technical field [0001] The present application relates to the field of image processing, in particular to a compression method, an electronic device and a storage medium for labeling data. Background technique [0002] In the commonly used medical image annotation data processing process, the existing medical image annotation data transmission mainly has the following two forms: (1) directly transmit the original three-dimensional volume data; (2) use the encoding algorithm to compress the annotation data transfer afterwards. And all there is following weak point in these two kinds of methods: [0003] The first transmission method will consume a large amount of storage space and a long transmission time due to the large amount of labeled data, resulting in low transmission efficiency. [0004] The second transmission method often utilizes two encoding methods, lossy encoding and lossless encoding. In order to keep the original labeled data consistent with the encoded and...
