Hi, Finally I solved the opencv and face detector issue setting up the environmet on windows.
Besides, I think I solved face detector chrome compatibility on google chrome. There was a javascript error in this line: resultImageData = new ImageData(temp1, width, height); //for chrome this line is an illegal constructor. resultImageData= ctx.createImageData(width, height); In the kaku_helper function I put this resultImageData.data.set(temp1); before to ctx.putImageData(resultImageData, 0, 0); The .data of ImageData instances invocated by new(), maintains the pointer of temp1, that's why the canvas is rendering fine, but only in firefox. Using ctx.createImageData, the contex has reserved other memory address, so resultImageData.data.set(temp1) only copies the value of temp1. Is a little bit unstable, sometimes is working at 25 fps, rarely works in 3 fps, and in few cases doesn't open the camera. About the performance, I know that this is not the best way to do it, but I haven't found any better solution.
