I plotted some dots on a white image by using draw.ellipse in PIL
我在PIL中使用draw.ellipse在白色图像上绘制了一些点
draw.ellipse((x[i][j] - 2, y[i][j] - 2, [i][j] + 2, [i][j] + 2), fill='black', outline='black')
((x,y) is a coordinate of the plot)
((x,y)是图的坐标)
Then I found some noise around the plots like this:
然后我在这些地块周围发现了一些噪音:
How can I get rid of them?
