技術說明

一種視訊除霧處理方法，包含：由影像擷取模組擷取包含複數個輸入像素的霧氣影像；由大氣光估測單元根據輸入像素計算大氣光值；由天空估測單元根據輸入像素透過導向濾波器的中間計算結果判斷天空影像區域；由暗通道先驗單元根據輸入像素基於暗通道先驗計算影像暗通道；由透射圖估測單元根據輸入像素、大氣光值、天空影像區域及該影像暗通道透過導向濾波器計算細化透射圖；由影像除霧單元根據輸入像素、大氣光值及細化透射圖產生除霧影像；以及由影像輸出模組輸出除霧影像。 A video dehazing method includes: capturing a hazy image including multiple inputted pixels by an image capture module, calculating an atmospheric light value according to the inputted pixels by an atmospheric light estimation unit, determining a sky image area according to the inputted pixels via the intermediate calculation results of a guide filter by a sky detection unit; calculating a dark channel image according to the pixels based on dark channel prior (DCP) by a dark channel prior unit; calculating a fine transmission image according to the pixels, the atmospheric light value, the sky image area and the dark channel image via a guide filter by a transmission estimation unit, generating a dehazing image according to the pixels, the atmospheric light value and the fine transmission image by an image dehazing unit, and outputting the dehazing image by a video outputting module.
