例程讲解-03-grayscale_bilateral_filter灰度双边滤波

# 双边滤波例程
# 此示例显示了在灰度图像上使用双边滤波。

import sensor, image, time

sensor.reset() # Initialize the camera sensor.
sensor.set_pixformat(sensor.GRAYSCALE) # or sensor.RGB565
sensor.set_framesize(sensor.QQVGA) # or sensor.QVGA (or others)
sensor.skip_frames(time = 2000) # Let new settings take affect.
clock = time.clock() # Tracks FPS.

while(True):
    clock.tick() # Track elapsed milliseconds between snapshots().
    img = sensor.snapshot() # Take a picture and return the image.

    # color_sigma controls how close color wise pixels have to be to each other to be
    # blured togheter. A smaller value means they have to be closer.
    # A larger value is less strict.

    # space_sigma controls how close space wise pixels have to be to each other to be
    # blured togheter. A smaller value means they have to be closer.
    # A larger value is less strict.

    # Run the kernel on every pixel of the image.
    img.bilateral(3, color_sigma=0.1, space_sigma=1)

    # Note that the bilateral filter can introduce image defects if you set
    # color_sigma/space_sigma to aggresively. Increase the sigma values until
    # the defects go away if you see them.

    print(clock.fps()) # Note: Your OpenMV Cam runs about half as fast while
    # connected to your computer. The FPS should increase once disconnected.
