示例1: getMP
# 需要导入模块: import General [as 别名]
# 或者: from General import getDifferenceArray [as 别名]
def getMP(track, **kwargs):
travel = []
xDiffs = gen.getDifferenceArray(track.x)
yDiffs = gen.getDifferenceArray(track.y)
for x, y in zip(xDiffs, yDiffs):
travel.append(gen.pythagorean(x, y))
totalTravel = np.sum(travel)
xDistance = track.x[-1] - track.x[0]
yDistance = track.y[-1] - track.y[0]
if totalTravel == 0:
return 0
return gen.pythagorean(xDistance, yDistance) / totalTravel示例2: getDirectionality
# 需要导入模块: import General [as 别名]
# 或者: from General import getDifferenceArray [as 别名]
def getDirectionality(track, **kwargs):
FIELD_VECTOR = kwargs['gradientVector']
xDiffs = gen.getDifferenceArray(track.x)
yDiffs = gen.getDifferenceArray(track.y)
directedness = []
#calculate instantenous directionality between frames
for dx, dy in zip(xDiffs, yDiffs):
vector = [dx, dy]
normVector = gen.normalizeVector(vector)
if normVector != 0:
normFieldVector = gen.normalizeVector(FIELD_VECTOR)
directionality = gen.dotProduct(vector, FIELD_VECTOR) / normVector * normFieldVector
directedness.append(directionality)
else:
directedness.append(0)
return gen.nanMean(directedness)
