Multi-scale multi-modal micro-expression recognition algorithm based on transformer

no code implementations8 Jan 2023 Fengping Wang, Jie Li, Chun Qi, Lin Wang, Pan Wang

A micro-expression is a spontaneous unconscious facial muscle movement that can reveal the true emotions people attempt to hide.

Reconstruction of compressed spectral imaging based on global structure and spectral correlation

no code implementations27 Oct 2022 Pan Wang, Jie Li, Jieru Chen, Lin Wang, Chun Qi

To take full exploration of the constraints between spectra, the coefficients corresponding to the convolution kernel are constrained by the L_(2, 1)norm to improve spectral accuracy.

A Dynamic 3D Spontaneous Micro-expression Database: Establishment and Evaluation

no code implementations31 Jul 2021 Fengping Wang, Jie Li, Siqi Zhang, Chun Qi, Yun Zhang, Danmin Miao

Micro-expressions are spontaneous, unconscious facial movements that show people's true inner emotions and have great potential in related fields of psychological testing.

CNN Retrieval based Unsupervised Metric Learning for Near-Duplicated Video Retrieval

no code implementations30 May 2021 Hao Cheng, Ping Wang, Chun Qi

As important data carriers, the drastically increasing number of multimedia videos often brings many duplicate and near-duplicate videos in the top results of search.

Kernel based low-rank sparse model for single image super-resolution

no code implementations27 Sep 2018 Jiahe Shi, Chun Qi

Under the assumption that the sparse coeffcients for the nonlocal data in the kernel space should be low-rank, we impose low-rank constraint on sparse coding to share similarities among representation coeffcients and remove outliers in order that stable weights for SR reconstruction can be obtained.
