The presence of noise in a high dynamic range (HDR) synthesis poses a serious degradation to the HDR image especially when the input images are captured at low light condition or with high sensitivity settings. Thus, a two-dimensional (2D) denoising factor is proposed to assign higher weight to a pixel with less noise based on both pixel luminance and image exposure. This pure temporal denoising factor is controlled by two key coefficients and can preserves edge and fine detail without blurring artifact. In addition, both memory and computation time are significantly reduced compare to other denoising methods.
