ovl.target_filters.sorters module

ovl.target_filters.sorters.area_sort(contour_list, descending_sort=True)

Sorts the list of contours by contour sort, default is from large to small

Parameters:

• contour_list – the list of contours to be sorted, list of ndarrays
• descending_sort – a flag that reverses the sort order set to

Returns:

the sorted contour list

ovl.target_filters.sorters.circle_sort(contour_list, area_limit=0.9, radius_limit=0.8)

Sorts the list of contours according to how much they are circle from most similar to least using the circle rating function.

Parameters:

• contour_list (list or one contour(numpy array)) – list of Contours to filter
• area_limit – The area limit for the circle rating, look at Geometry.circle_rating
• radius_limit – the radius limit for the circle rating, look at Geometry.circle_rating

Returns:

the list sorted by circle rating

ovl.target_filters.sorters.dec_area_sort(contour_list)

Sorts the list of contours from the largest to the smallest based on area of the contour

Parameters:contour_list – List of Contours to be sorted Returns:the contour list sorted.

ovl.target_filters.sorters.dec_length_sort(contour_list)

Sorts the list of contours from the largest to the smallest based on area of the contour

Parameters:contour_list – List of Contours to filter Returns:the contour list sorted.

ovl.target_filters.sorters.distance_sort(contour_list, point)

Sorts the contours according to their distance from the NOTE: it is important to area filter before image_center_sort

Parameters:

• contour_list (List or one contour (numpy array)) – The list of contours to be sorted
• point – the point from which the distance of all contours are sorted by

Returns:

the sorted contour list

ovl.target_filters.sorters.image_center_sort(contour_list, image_dimensions=(320, 240))

Sorts the contours from the closest to the center to the farthest. NOTE: it is important to area filter before image_center_sort

Parameters:

• contour_list – list of contours to be sorted
• image_dimensions – the dimensions of the image

Returns:

ovl.target_filters.sorters.inc_area_sort(contour_list)

Sorts the list of contours from the smallest to the largest based on area of the contour

Parameters:contour_list – List of Contours to filter Returns:the contour list sorted.

ovl.target_filters.sorters.inc_length_sort(contour_list)

Sorts the list of contours from the smallest to the largest based on area of the contour

Parameters:contour_list – List of Contours to filter Returns:the contour list sorted.
