I read a piece of writing in the document of "image.find_blobs"function:"thresholds must be a list of tuples [(lo, hi), (lo, hi), …, (lo, hi)] defining the ranges of color you want to track. You may pass up to 16 threshold tuples in one image.find_blobs call. ",here “16” is an error? i am confused!
Each threshold tuple is 6 values for RGB565 and 2 values for GRAYSCALE. You can then have a list of up to 16 thresholds to segment the image by. Find blobs will then return a list of blobs which includes blobs from all passed thresholds.
threshold0 = [125, 125, 125, 125, 125, 125]
threshold1 = [130, 130, 130, 130, 130, 130]
threshold15 = [230, 230, 230, 230, 230, 230]
list_of_thresholds = [threshold0, threshold1, …, threshold15]
Thanks! Gotcha that!
I notice that there is a new function “image.finc_blobs”,but i can’t find any definition information in the doc,could you please tell me the prototype of this function?
That would be an error. There’s only a find_blobs function. Where’s that error?
Thanks for your reply
I found this error at http://docs.openmv.io/library/omv.image.html#id3!
