This demo is using to MCP-based MSI-CS reconstruction. All MSI dataset can be downloaded at the following linking: https://pan.baidu.com/s/1LHILMjpdktqWsFTw0RU2vQ Extract code：1234 When you use this demo, please first load software package "matconvnet", and make sure run the function "vl_compilenn.m" succesfully. Later, you can directly run the function "MCP_MSI_CS_Demo.m" Currently, this demo can be directly runned by using any CPU. Note that: If you cannot conduct the function "vl_compilenn.m" succesfully. Please do the following operator: In function "FFD_Net_Denoiser.m", please transform " res = vl_ffdnet_concise(net, input);" into "res = vl_ffdnet_matlab(net, input);". but this operator is very slow.
