Few-shot Adaptive Object Detection with Cross-Domain CutMix
In object detection, data amount and cost are a trade-off, and collecting a large amount of data in a specific domain is labor-intensive. Therefore, existing large-scale datasets are used for pre-training. How...

Rethinking Generic Camera Models for Deep Single Image Camera Calibration to Recover Rotation and Fisheye Distortion
Although recent learning-based calibration methods can predict extrinsic and intrinsic camera parameters from a single image, the accuracy of these methods is degraded in fisheye images. This degradation is ca...

Classification of Photometric Factors Based on Photometric Linearization
We propose a new method for classification of photometric factors, such as diffuse reflection, specular reflection, attached shadow, and cast shadow. For analyzing real images, we utilize the photometric linea...
