示例1: findRoi

# 需要导入模块: from box import Box [as 别名]
# 或者: from box.Box import getContourRep [as 别名]
def findRoi(filename):

	image = cv.imread(filename)
	image = cv.resize(image, (0, 0), fx = 0.2, fy = 0.2) # TODO: Just set a general bound on image size

	gray = cv.cvtColor(image, cv.COLOR_BGR2GRAY)
	ret, thresh = cv.threshold(gray,0,255,cv.THRESH_BINARY_INV + cv.THRESH_OTSU)

	LOWAREA_THRESH = 10 
	UPAREA_THRESH = 3000
	contours, heirachy = cv.findContours(thresh, cv.RETR_TREE, cv.CHAIN_APPROX_SIMPLE)

	contours = [con for con in contours if LOWAREA_THRESH < cv.contourArea(con) < UPAREA_THRESH]
	contours = [cv.approxPolyDP(con, 10, True) for con in contours]
	contours = [cv.convexHull(con) for con in contours]
	contours = [con for con in contours if len(con) != 1]

	# After initialization, follow this algorithm:
	# 1. Consider a box B in the set.
	# 2. For every other box C in the set
	# 3. If dist(B, C) < THRESHOLD, meld B's set with C's set
	# 4. Repeat for each box C
	# 5. For each disjoint set, meld each box in the set together. These are your clusters.

	objects = []
	for i, con in enumerate(contours):

		box = Box(x, y, w, h)
