Microsoft patents method to describe irregular shapes using angles
Microsoft has filed a patent application for a method that converts the outline of an irregular object in a digital image into a compact data code. The system splits the shape into smaller sections and calculates specific angle measurements for each boundary to create this description.
In the filing’s own words
A method performed by a processor of a computing system is described herein, where the method includes obtaining an image that includes an object having a shape, where a boundary of the shape of the object in the digital image is labeled in the digital image. The method also includes computing an encoding for the shape, where computing the encoding for the shape includes partitioning the shape into multiple partitions. Computing the encoding for the shape further includes, for the multiple partitions, computing angle-based contour descriptors that represent boundaries of the partitions, where the encoding for the shape of the object is based upon the angle-based contour descriptors.
What exactly they claim (claim 1)
1. A computing system comprising: a processor; and memory storing instructions that, when executed by the processor, cause the processor to perform actions comprising: obtaining a digital image that includes an object having a shape, a boundary of the shape of the object in the digital image being labeled in the digital image; and generating an encoding for the shape of the object by: identifying a mass center of the shape; computing a line of partition that passes through the mass center of the shape; partitioning the shape into a first shape and a second shape along the line of partition; computing a first angle-based contour descriptor that represents a boundary of the first shape; computing a second angle-based contour descriptor that represents a boundary of the second shape; and encoding the shape of the object based upon the first angle-based contour descriptor and the second angle-based contour descriptor.
