[0057] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0058] A METHOD OF THE PRESENT INVENTION IS BASED ON ARR IMAGE COMPRESSION METHOD BASED ON A PRIOR ARCHITECTURE, COMPRISING THE FOLLOWING STEPS:
[0059] Step 1: Construction of a self-codec convolutional network.
[0060] The self-codec network is divided into three parts: one part is the encoder, the encoder completes the compression encoding of the SAR image through multi-layer convolution, adjusts the number of layers, steps and number of channels of the convolution to control the corresponding compression ratio; the second part is the arithmetic codec, the arithmetic codec generates the binary stream according to the distribution of the image signal, and further compresses the number of bits; the last part is the decoder, and the decoder completes the decoding of the encoded image through multi-layer transpose convolution. The design of the c...
