Existing methods for imaging through scattering media prioritize grayscale and often falter in resolving multispectral speckles, leading to inadequate spectral recovery. We propose a method that establishes a spectral component separation model for high-quality multispectral imaging through scattering media and around corners. By leveraging the uncorrelation among speckles of different wavelengths and the superposition essence of multispectral speckles, a multispectral speckle simplex with speck...
