Learning Underwater Image Enhancement Iteratively Without Reference Images

AAAI 2026technical

Since high-fidelity reference images are difficult to obtain in real underwater scenes, most deep models trained by synthetic paired data cannot match real-world data exactly. In this paper, we propose an unsupervised training framework for underwater image enhancement (UIE) by leveraging an iterati

Revisiting Optimal Coding for I-ToF under Practical Sensor Constraints

CVPR 2026

The depth precision of an indirect time-of-flight (I-ToF) camera is highly dependent on its coding scheme. However, identifying the optimal coding scheme is challenging due to the infinitely many possible combinations of modulation and demodulation functions. Although previous works have derived dep
