Results of a multidimensional scaling performed on the correlation of Munsell representations for different layers of DeepCC, from convolutional layer 1 (Conv1) to fully connected layer 2 (Fc2). Each column corresponds to one layer, each row to the different dimensions resulting from the MDS: first row, Dimensions 1 and 2 of maximal variance (decreasing order); second row, Dimensions 2 and 3 of maximal variance (decreasing order). Each dot corresponds to one Munsell surface, displayed with its color under the D65 illumination. While Munsell surfaces appear clustered in the early layers, particularly with respect to lightness, a progressive disentanglement in terms of chromaticity and lightness takes place throughout the network.
