卷积计算器，计算x(n)=1(0<=n<=N1),y(n)=0.5*n(0<=n<=N2)相卷积的结果，其中两者长度可调，并绘制出图像，计算最大值-Paint a convolution picture and find out the maximum value.

Java_图像处理(几何变换、色彩变换、卷积、频率变换)-Java_ image processing (geometric transformation, color transform, convolution, frequency conversion)

该代码建立了一个窗口作为平台，在上面显示图像的一些基本处理，如二值化，卷积模糊，利用sobel算子提取边缘等等(The code builds a window as a platform on which some basic processing of the image is displayed, such as binarization, convolution blur, using the sobel operator to extract the edges, etc.)
