Abstract
In a data processing method executed by a data processing system that performs compression and/or decompression of image data, a tensor shape representing compression target data is obtained, compression processing is performed using data having an input shape fixed for each shape of the compression target data as input, and an input shape fixed compressor for outputting compressed data is generated. Then, the data processing system performs compression processing of compression target data using the generated input shape fixed compressor to generate compressed data.
Claims14
A data processing method executed by a data processing system including a processor that performs compression and/or decompression of image data, the processor executing steps comprising:
- obtaining a shape of a tensor representing compression target data;
- generating an input shape fixed compressor that outputs compressed data by executing compression processing using image data having a fixed input shape for each shape of the compression target data as input;
- generating the compressed data by executing the compression processing of the compression target data using the generated input shape fixed compressor;
- executing the compression processing of the compression target data using the input shape fixed compressor when there is an input shape fixed compressor corresponding to the input shape that matches the shape of the obtained compression target data;
- and
- executing the compression processing of the compression target data using the general-purpose shape compressor that outputs compression data by executing the compression processing using data having any of the input shapes as input if there is no input shape fixed compressor corresponding to the input shape that matches the shape of the obtained compression target data.
