Determining whether a blob is detected

How would you determine whether a blob is detected or not. For example, i want to detect an orange object and display when it is detected so how would i do that?

Hi, please see the Examples->Color Tracking in OpenMV IDE. The find_blobs() method detects blobs and returns a list of color blobs in the image. If the threshold you pass for the color you want to detect is found then the list of blobs will not be empty.
