Rate adaptive coding and decoding scheme for preferentially segmented data

A method in a rate adaptation system includes: classifying, by an encoder, a plurality of data clusters in a segmented image into one of a plurality of categories corresponding to different predetermined tags having a predetermined priority; vectorizing, by the encoder, the data to generate a sparse vector xi for its corresponding tag; encoding, by an encoder, a plurality of sparse vectors xi by multiplying the measurement matrix Ai (t) with the sparse vectors xi to generate a set of encoding information yi; sending, by the encoder, a plurality of groups of encoded information yi to the decoder in a priority order; decoding, by the decoder, the plurality of sets of encoded information yi to determine the plurality of sparse vectors xi based on determining a measurement matrix Ai (t); and combining the plurality of sparse vectors xi into a single image frame. 一种速率自适应系统中的方法，包括：由编码器将分段图像中的多个数据簇分类为对应于具有预定优先级的不同预定标签的多个类别之一；由编码器对数据进行矢量化，以生成用于其对应标签的稀疏矢量xi；由编码器通过将测量矩阵Ai(t)与稀疏矢量xi相乘以生成一组编码信息yi来编码多个稀疏矢量xi；由编码器向解码器以优先顺序
