For zero-shot image restoration, we design a novel model, termed SiamTrans, which is constructed by Siamese transformers, encoders, and decoders.
One is a 1D weight vector used for image-level scenario adaptation, the other is a 3D weight map aimed for pixel-wise category fusion.
The frequency-guided upsampling module reconstructs details from multiple frequency-specific components with rich details.

This challenge is based on a newly collected validation and testing image datasets, and hence, named SIDD+.
The proposed BlendMask can effectively predict dense per-pixel position-sensitive instance features with very few channels, and learn attention maps for each instance with merely one convolution layer, thus being fast in inference.

The temporal consistency loss is combined with the spatial loss to update the model in an end-to-end fashion.
Ranked #4 on Monocular Depth Estimation on Mid-Air Dataset
Monocular depth prediction plays a crucial role in understanding 3D scene geometry.
Ranked #11 on Monocular Depth Estimation on KITTI Eigen split
To tackle this dilemma, we propose a knowledge distillation method tailored for semantic segmentation to improve the performance of the compact FCNs with large overall stride.
In this work, we propose a data-dependent upsampling (DUpsampling) to replace bilinear, which takes advantages of the redundancy in the label space of semantic segmentation and is able to recover the pixel-wise prediction from low-resolution outputs of CNNs.
