Gated Dehazing Network via Least Square Adversarial Learning.

Area of Science:

• Computer Vision
• Image Processing
• Artificial Intelligence

Background:

• Hazy environments significantly reduce visibility and object identification.
• Existing atmospheric scattering model estimation methods can lead to distortions due to inaccurate model estimations.
• Dehazing techniques are crucial for restoring image quality in adverse weather conditions.

Discussion:
