      4. Total variation de-mosaicing. A color image is represented by 3 m nmatrices R, G, and Bthat give the red, green, and blue pixel intensities. A camera sensor, however, measures only one of the color intensities at each pixel. The pattern of pixel sensor colors varies, but most of the patterns have twice as many green sensor pixels as red or blue.

The order in which the data instances arrive matters: since Somoclu uses multiple cores, there is no control over the order of each batch, hence the maps will show small variation even with a PCA initalization. We can also postprocess the codebook with an arbitrary clustering algorithm that is included inscikit-learn. The

      For every plotted curve, there is an optional argument that is a format string indicating the color and line type of the plot. The letters and symbols of the format string are from MATLAB, and are composed of a color indicator followed by line style indicator. The default format string is 'b-', which, as we have seen is a solid blue line.
