Image reconstruction method and device, medium, and product

An image reconstruction method, comprising:

• inputting a RAW image captured by an event camera into a target image reconstruction model to obtain a color image, wherein the target image reconstruction model comprises an encoding module, a decoding module, and a reconstruction module that are sequentially connected;
• wherein
• the inputting a RAW image captured by an event camera into a target image reconstruction model to obtain a color image comprises:
• inputting the RAW image into the encoding module to obtain a downsampled feature map, wherein the encoding module comprises a plurality of Swin Transformer modules connected in series, and the Swin Transformer modules in the encoding module are connected through a patch merging layer;
• inputting the downsampled feature map into the decoding module to obtain an upsampled feature map, wherein the decoding module comprises a same quantity of Swin Transformer modules as the encoding module, and the Swin Transformer modules in the decoding module are connected through a patch expanding layer;
• and the encoding module and the decoding module are structurally symmetrical, and the Swin Transformer modules in the encoding module are connected to the Swin Transformer modules in the decoding module through skip connections;
• and
• inputting the upsampled feature map into the reconstruction module for reconstruction to obtain the color image.
