WebIn this paper, an effective fusion-based foggy image restoration technique by using dual tree complex wavelet transform (DT-CWT) has been proposed. Minimum color channel and the dark channel of a foggy image are constructed. Low and high pass components of both these channels are fused to obtain a transmission map. WebJun 17, 2024 · Specifically, dual-tree complex wavelet transform is exploited to obtain six directional features (±75°, ±45°, ±15°) of different frequency components from original images, and a direction correlation extraction (DCE) block is presented to capture the direction correlation.
