摘要
Systems and methods for rendering depth-of-field visual effect on images with high computing efficiency and performance. A diffusion blurring process and a Fast Fourier Transform (FFT)-based convolution are combined to achieve high-fidelity depth-of-field visual effect with Bokeh spots in real-time applications. The brightest regions in the background of an original image are enhanced with Bokeh effect by virtue of FFT convolution with a convolution kernel. A diffusion solver can be used to blur the background of the original image. By blending the Bokeh spots with the image with gradually blurred background, a resultant image can present an enhanced depth-of-field visual effect. The FFT-based convolution can be computed with multi-threaded parallelism.
