示例1: dense_image_warp
# 需要导入模块: import cv2 [as 别名]
# 或者: from cv2 import convertMaps [as 别名]
def dense_image_warp(im, dx, dy, interp=cv2.INTER_LINEAR):
map_x, map_y = deformation_to_transformation(dx, dy)
do_optimization = (interp == cv2.INTER_LINEAR)
# The following command converts the maps to compact fixed point representation
# this leads to a ~20% increase in speed but could lead to accuracy losses
# Can be uncommented
if do_optimization:
map_x, map_y = cv2.convertMaps(map_x, map_y, dstmap1type=cv2.CV_16SC2)
remapped = cv2.remap(im, map_x, map_y, interpolation=interp, borderMode=cv2.BORDER_REFLECT) #borderValue=float(np.min(im)))
if im.ndim > remapped.ndim:
remapped = np.expand_dims(remapped, im.ndim)
return remapped 示例2: dense_image_warp
