Abstract: A process to isolate objects of interest in an image uses a model which takes into account the artifacts stemming from the JPEG compression. The pixels are sorted accordingly to layers which regroup pixels of similar value, and the background is modeled by a polygon from an additional picture. Segmentation based on the knowledge of the background and the layers is then performed. This method provides good results for segmentation, while being sufficiently fast to be implemented for real time application.

Abstract: An apparatus for measuring the dimensions of human feet is comprised of a base and a cover, which fits over it to define the borders of two essentially rectangular wells into which the feet to be measured are placed. A pressure pad assembly comprising a matrix of sensors is placed at the bottom of base. The walls of the wells are defined by PCBS comprising arrays comprised of a multitude of emitter/detector pairs, which are used to make length and width measurements of said feet. MCUs on the pressure pad assembly and computation means comprise software algorithms that automatically make length, width, and pressure measurements and correct errors in the length and width measurements caused by misalignment of the feet in the wells. Methods of using the apparatus are also presented.

Abstract: The invention presents an apparatus for measuring the dimensions of human feet. The apparatus is comprised of a base (20) and a cover (2), which fits over it to define the borders of two essentially rectangular wells (3, 31) in the upper surface of said base, into which the feet to be measured are placed. Pressure pads (5, 5?) containing a sensor are placed at the bottom of each well and the perimeters of the well, are surrounded by arrays comprised of a multitude of emitter/detector pairs, which are used to make length and width measurements of said feet. In addition, computational means, which calculate the dimensions of the feet from data from the pressure pads and emitter/detector pairs and display means are provided.
