利用拉普拉斯算子进行图像的锐化

基于OpenMV平台进行开发

程序结构的主要特点：

1.利用卷积运算

图像锐化的结果：

程序代码：

import sensor, image, time

kernel_size = 1 # kernel width = (size*2)+1, kernel height = (size*2)+1

kernel = [-1, -1, -1,\

          -1, +9, -1,\

          -1, -1, -1]

# This is a sharpen filter kernel.

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(10) # 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.morph(kernel_size, kernel)
