Abstract
A method of adjusting the color of images captured by a plurality of cameras comprises the steps of receiving a first image captured by a first camera from the plurality of cameras, analyzing the first image to separate the pixels in the first image into background pixels and foreground pixels, selecting pixels from the background pixels that have a color that is a shade of gray, determining the amount to adjust the colors of the selected pixels to move their colors towards true gray, and providing information for use in adjusting the color components of images from the plurality of cameras.
Claims18
A method of adjusting the color of images captured by a plurality of cameras comprising the steps of:
- receiving a first image captured by a first camera from the plurality of cameras;
- analyzing the first image to separate the pixels in the first image into background pixels and foreground pixels;
- selecting pixels from the background pixels that have a color that is a shade of gray;
- determining the amount to adjust the colors of the selected pixels to move their colors towards true gray;
- and providing information for use in adjusting the color components of images from the plurality of cameras.
A system for adjusting the color of images captured by a plurality of cameras comprising:
- a network;
- a plurality of cameras connected to the network;
- and a processor connected to the network and being adapted to receive a first image captured by a first camera from the plurality of cameras, to analyze the first image to separate the pixels in the first image into background pixels and foreground pixels to select pixels from the background pixels that have a color that is a shade of gray, to determine the amount to adjust the colors of the selected pixels to move their colors towards true gray, and to provide information for use in adjusting the color components of images from the plurality of cameras.
A non-transitory computer readable medium comprising instructions configured to cause a processor to:
- receive a first image captured by a first camera from a plurality of cameras;
- to analyze the first image to separate the pixels in the first image into background pixels and foreground pixels;
- to select pixels from the background pixels that have a color that is a shade of gray;
- to determine the amount to adjust the colors of the selected pixels to move their colors towards true gray;
- and to provide information for use in adjusting the color components of images from the plurality of cameras.
