Abstract
Provided is a method and apparatus for detecting multi moving objects in high resolution image sequences and performs moving objects on a screen using a general image collecting apparatus. The present invention provides a method of effectively removing the background of moving objects like motion of a leaf or reflection of a wave in an outdoor environment using a statistical method and uses a GPU installed in a general computer to process high resolution image sequences at high speed.
Claims18
A method for processing image data based on a Gaussian Mixture Model (GMM), comprising:
- collecting image data;
- performing initialization on the standard deviations, variance, mean, and weights of each model;
- converting an input image into a desired color space;
- and
- processing the image data based on the converted color space.
The method for processing image data according to claim 2, wherein the processing the image data sets the weight for each image channel of the input image to calculate a channel reflecting distance value (Dist).
The method for processing image data according to claim 3, wherein the processing the image data classifies a pixel as a background or an object based on the calculated channel reflecting distance value.
A system for detecting an object, comprising:
- a color space converter that converts a color space of an input image into a target color space to which weights for each channel are assigned;
- a data processor that processes data of the input image based on the weights;
- and
- a post processor that removes noise in the processed image to emphasize a moving object.
