示例1: getAvgMov
# 需要导入模块: import General [as 别名]
# 或者: from General import nanMean [as 别名]
def getAvgMov(track, **kwargs):
SPEED_CONVERSION_FACTOR = kwargs["speedConversionFactor"]
avgMov = []
diff = []
frameDistanceBetweenFrames = []
positionalDistanceBetweenFrames = []
for index in range(0, len(track.x) - 1):
#the number of frames by which two adjacent elements in track are separated
frameDistanceBetweenFrames = track.t[index + 1] - track.t[index]
#the absolute positional distance between adjacent tracked frames
positionalDistanceBetweenFrames = gen.getDistance(track.x[index], track.x[index + 1], track.y[index], track.y[index + 1])
#the distance traveled per frame between adjacent tracked frames
diff.append(positionalDistanceBetweenFrames / frameDistanceBetweenFrames)
return gen.nanMean(diff) * SPEED_CONVERSION_FACTOR示例2: getDirectionality
# 需要导入模块: import General [as 别名]
# 或者: from General import nanMean [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)
