A Generative Statistical Algorithm for Automatic Detection of Complex Postures
(A) Head (cyan) and body (yellow) features of an egl-30 mutant, as determined by the basic algorithm. (B) Same as (A) with added double-body (magenta) features, as determined by the improved algorithm. (C) Coarse detection of the posture of the egl-30 mutant using the improved algorithm. (D) Fine detection of the posture of the egl-30 mutant. (E) Examples of non-self-avoiding postures detected in six mutants that exhibit coiler phenotypes. The midline and edges of the animal are depicted in green and red, respectively. Scale bars represent 100 μm.
