US 2013/0156299 A1 · METHOD AND APPARATUS FOR DETECTING PEOPLE WITHIN VIDEO FRAMES BASED UPON MULTIPLE COLORS WITHIN THEIR CLOTHING

Abstract

A video analytic device performs a method for detecting people within frames of video based upon multiple colors within their clothing. The method includes: receiving a frame of video; and determining that a first color region within the frame matches a first color of interest for a clothing uniform, wherein the determining is based on a first set of color representation constraints. The method further includes determining that a second color region within the frame matches a second color of interest for the clothing uniform, wherein the determining is based on a second set of color representation constraints and the first and second colors of interest are different. In addition, the method includes applying a set of geometric constraints to the first and second color regions to determine a count of people within the frame wearing the clothing uniform.

Dependent claims

A method, performed in a video analytic device, for detecting people within frames of video based upon multiple colors within their clothing, the method comprising:

receiving a current frame of video;
determining that a first color region within the current frame matches a first color of interest for a clothing uniform, wherein the determining is based on a first set of color representation constraints;
determining that a second color region within the current frame matches a second color of interest for the clothing uniform, wherein the determining is based on a second set of color representation constraints, wherein the first and second colors of interest are different;
and
applying a set of geometric constraints to the first and second color regions to determine a count of people within the current frame wearing the clothing uniform.

A non-transient computer-readable storage element having computer readable code stored thereon for programming a computer to perform a method for detecting people within frames of video based upon multiple colors within their clothing, the method comprising:

receiving a current frame of video;
detecting, within a first resolution image of the current frame, multiple colors of interest to identify a first set of pixels of interest;
classifying, within a second and higher resolution image of the current frame, colors of a second set of pixels of interest to identify pixels of the multiple colors of interest, wherein the second set of pixels of interest correspond to the first set of pixels of interest;
determining a set of color regions within the second and higher resolution image, wherein each of the color regions within the set contains at least one of the pixels of the multiple colors of interest;
and
verifying that the set of color regions conform to a set of geometric constraints to determine a count of people, within the current frame, wearing a same type of clothing having the multiple colors of interest.
