can not load cross-origin data with canvas.getImageData()

[RachelYun]

When I load image from other site(I have to do that), canvas throw Error like " Uncaught SecurityError: Failed to execute 'getImageData' on 'CanvasRenderingContext2D': the canvas has been tainted by cross-origin data. ",
after I do some research , I know it should not put image.src = URL before canvas.drawImage,but computeSegmentation need real imageData.

What can I do with this issue??

P.S. I must use this site image and can not save it on local

This is a security feature of web browsers and there is no simple workaround unless CORS is enabled in the image server.
