%X In order to measure the displacement of the foot joints under different press and further study their movement trait, the displacement of each marker in the foot marker images needs to be calculated. The black markers and rectangular region in the experiment images are the probes and scale. In this paper, scale extraction and the automatic pixel measurement of a foot marker image were realized. First, the authors extracted the border of scale according to the linear least squares method and computed the pixel distance between the two endpoints at the bottom of the scale, then calculated the actual length that each pixel represented and realized the automatic conversion between pixel distance and the length of the scale, which provided service for diagnosis and treatment of the foot diseases.
