為了實(shí)現(xiàn)夜間圖像的實(shí)時(shí)增強(qiáng)，本文設(shè)計(jì)了基于DSP 的夜間圖像實(shí)時(shí)增強(qiáng)系統(tǒng)，然后對Ardely 提出的DADPEQU 夜間圖像增強(qiáng)方法進(jìn)行了改進(jìn)，提出了基于有效黑暗連通集的增強(qiáng)算法，取得了較為滿意的增強(qiáng)效果。在設(shè)計(jì)的實(shí)時(shí)圖像增強(qiáng)系統(tǒng)上對夜間視頻圖像實(shí)時(shí)增強(qiáng)進(jìn)行了嘗試，結(jié)果表明，本文的方法既能取得較好的增強(qiáng)效果，又能滿足實(shí)時(shí)的處理要求。

Abstract: This paper designed a real-time night image enhancing system based on DSP. Paper improved Ardely’s enhancement algorithm which is called DADPEQU first, then give a new enhancing algorithm base on useful and dark connected set. Author tried to enhance the night video with the improved algorithm base on parallel processing system. The system is proved to be efficient in real-time night image enhancing system.
