Do you have many moving red objects in your training data? You should make sure your training data has examples of all the types of things you want to be able to separate.

Without your complete pipeline and some examples, it is kind of impossible to say why they get detected. My best guess based on your previous posts, is that you are using HSV color based pixel classification. Probably your ranges are too close to the HSV values for moving red objects. As long as you stick to color only, you will never solve this issue.

hsv is better or rgb or ycrcb? im using: colorDetect(RGB based)+svm.predict

if i add red moving obj to negative,true alarms reduced

in my opinion, HSV seperates colors better than RGB, but still color based segmentation will only get you so far ...
