例程讲解-04-sharpen_filter图像锐化
本例程为04-image-Filters-sharpen_filter.py
本例程的目的是对图像进行morph变换，使图像达到锐化的效果。
# Sharpen Filter Example:
#
# This example demonstrates using morph to sharpen images.
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.
# Run the kernel on every pixel of the image.
img.laplacian(1, sharpen=True)
print(clock.fps()) # Note: Your OpenMV Cam runs about half as fast while
# connected to your computer. The FPS should increase once disconnected.
