nuclear filtering



    # Nuclear filtering
    # This example demonstrates nuclear filtering.
    import sensor, image, time
    sensor.reset() # Initialize the sensor
    #Set the image color format, there are RGB565 color map and GRAYSCALE grayscale
    sensor.set_pixformat(sensor.GRAYSCALE) # or sensor.RGB565
    #Set image pixel size
    sensor.set_framesize(sensor.QVGA) # or sensor.QQVGA (or others)
    sensor.skip_frames(time = 2000) # Let the new settings take effect
    clock = time.clock() # Track FPS frame rate
    kernel_size = 1 # 3x3==1, 5x5==2, 7x7==3, etc.
    kernel = [-2, -1, 0, \
              -1, 1, 1, \
               0, 1, 2]
        clock.tick() # Track the number of milliseconds that have passed between two snapshots().
        img = sensor.snapshot() # Take a picture and return the image
        # Run the kernel on every pixel of the image.
        # Run the kernel on each pixel of the image
        img.morph(kernel_size, kernel)
        print(clock.fps()) # Note: When connected to a computer, the frame rate will become half the speed. When the computer is not connected, the frame rate will increase.
