There is a visible difference between preview and output image frame sharpness in Mat and Frame transformation. The frame of the output image comes out is distinctly blurred.

Re: Mat and Frame output image frame sharpness
The preview and final image are computed at different resolutions - since the output image is anti-aliased for display it will generally look smoother than the preview image. To judge the true sharpness of the output image, view it at 1:1. At 1:4 which your screen shot indicates, 4x4 groups of image pixels are being averaged to produce each screen pixel.

Re: Mat and Frame output image frame sharpness
I can't reproduce it. The frame is tack sharp (at 1:1 viewing).
What settings do you use?

Re: Mat and Frame output image frame sharpness
That's true, at 1:1 it is sharp. I should have found that explanation myself.
