A Run-Length Encoding Approach for Path Analysis of C. elegans Search Behavior

Figure 1

Run-length encoding descriptor extraction: (a) video data for one worm tracking recording; (b) segmented images with worm body pixels shown in white; (c) worm body centroid extraction; (d) step-length, angle, and speed feature extraction; (e) movement pattern discovery (1 and 2 symbols represent the encoding of the path using clustering); (f) extraction of run-length encoding descriptors.
