inrangecv
Gets the handle Rto a binary image specifying which pixels are within the specified range.
Syntax
R = inrangecv(cvhandle, lower, upper)
Inputs
- cvhandle
- Handle of the image from a imreadcv command.
- lower
- Real vector or scalar containing lower bound element(s). Size of lower must be equal to the number of channels in the image represented by cvhandle.
- upper
- Real vector or scalar containing upper bound element(s). Size of upper must be equal to the number of channels in the image represented by cvhandle.
Outputs
- R
- Handle of the binary image showing specifying which pixels are in range. The output will be the same size as the image represented by cvhandle. Pixels in R will be 0 if they are not in the range and 255 otherwise.
Examples
img = imreadcv('Clouds.jpg', 1);
figure(1);
imshowcv(img);
white_ = [255, 255, 255];
lowerBound = [200,200,200];
mask = inrangecv(img, lowerBound, white_);
res = bitwiseandcv(img, img, mask);
figure(2);
imshowcv(res);
cvhandle = imreadcv('image1.jpg');
R = inrangecv(cvhandle, 0, 255);
cvhandle = imreadcv('image1.jpg');
R = inrangecv(cvhandle, [0 100 0], [255 255 255]);
