Spatially-variant Blur Degradation Model Based on Depth Estimation

Rui Xie, Shuzhan Guo, Li Zou, Jiaxiong Liu, Qian Wang, Jun Zhou

ICASSP 2025accepted

It is well known that the number of aligned images in the single image super-resolution (SISR) models training is limited. Synthesizing data is an effective way to address this issue. However, many degradation models only consider using spatially-invariant blur kernels to blur high-resolution (HR) i…

Neighborhood-Enhanced Multimodal Collaborative Filtering for Item Cold Start Recommendation

Guohui Li, Li Zou, Zhiying Deng, Qi Chen

ICASSP 2024accepted

The lack of interaction data of new items in recommendation systems leads to the problem of cold-start item recommendations. Current methods usually approximate content features of the items to interaction embeddings and then use content features for prediction. However, these methods typically lear…
