FREQUENCY DOMAIN EDGE ENHANCEMENT OF IMAGE CAPTURE - A simplified explanation of the abstract
- This abstract for appeared for US patent application number 17729561 Titled 'FREQUENCY DOMAIN EDGE ENHANCEMENT OF IMAGE CAPTURE'
Simplified Explanation
The abstract describes a technique for enhancing the edges in high dynamic range (HDR) images by analyzing the differences between different exposure frames. The method involves aligning an HDR frame with a frame of longer exposure time, adjusting the frame based on the alignment, estimating the gradient differences between image blocks in the HDR frame and the frame, and generating a merged frame that combines image data from both frames.
Original Abstract Submitted
Systems, methods, and non-transitory media are provided for frequency domain edge enhancement of multi-exposure high dynamic range (HDR) images. An example method can include determining an alignment between an HDR frame and a frame having an exposure time above a threshold; adjusting the frame based on the alignment; determining a gradient estimation map representing differences between image blocks in the HDR frame and image blocks in the frame; and generating, based on the gradient estimation map, a merged frame that includes a combination of at least some image data from the HDR frame and at least some image data from the frame.
