Rbgs (version 0.2)

staticdiff: Static frame difference background subtraction algorithm.

Description

This function implements a static background subtraction method in which background model is set to first frame. This static background model is then subtracted from all subsequent frames to obtain the forground images.

Usage

staticdiff(b, thresh)

Arguments

b

3-D matrix containing grayscaled video frames.

thresh

threshold required to obtain foreground images. Its value can lie between 30-40 or more depending upon the accuracy required.

Value

A 3-D matrix of frames containing foreground obtained after background subtraction is applied(binary images).

Examples

# NOT RUN {
 
# }
# NOT RUN {
videoURL <- system.file("extdata","daria_skip.avi",package = "Rbgs")
frames <- readvideoframe(videoURL,1,9)
bground<-staticdiff(frames,35) 
# }
