From: Superpixel-based segmentation of muscle fibers in multi-channel microscopy
A multi-channel microscopy image of muscle fibers. (a) Cyan channel; (b) Green channel; (c) Yellow channel; (d) Red channel; (e) Composite color image from all the four channels; (f) Composite color image from cyan, yellow and red channels after preprocessing. This section is from the same muscle of the cross-section in Fig. 1 a. Scalebars are 50 μ m. Each channel is a 12-bit image of 1024 × 1024 pixels
