Title: From Person Re-identification to Behaviour Analysis
Abs: The person re-identification is known to track persons across non-overlapping camera views and various methods have been developed recently. While behavious analysis is to understand a person’s activity, it seems that there is rare connection between these two tasks. This talk will try to show why person re-identification is useful for behavious analysis along with presenting our recent research on these two tasks.

Title: Object Cognition and Learning in complex environment
Abstract: Computer vision is closely related to brain science and cognitive science, but there is an insurmountable gap between human visual perception mode and computational visual computing methods, especially on key issues such as quantitative representation of human vision, computing architecture of cognitive learning. This report introduces our researches on complex environment understanding, three-dimensional target detection and driving behavior prediction with prototype memory and Gestalt cognition inspired by brain and cognition. Focusing on intelligent driving tasks, the report introduces three aspects: (1) Weakly-supervised and few-shot learning based semantic segmentation; (2) Thinking in 3D driving scene 3D target detection; (3) Predictive Bi LSTM CRF cognitive prediction of driving behavior.

Title: Local Correlated Analysis and Representation of Visual Media
Abs: Human beings have the inherent ability of local correlation and global aggregation. Visual media such as images/videos have the characteristics of rich content with complex contexts. Usually, local regions are the basic components of images, which contain rich information and various types of relationships. How to model the relationships between local regions and establish the multi-dimensional fusion from local to global is a cutting-edge problem in visual media analysis. In this work, we investigate the local correlation and global aggregation in the following aspects, including the contextual modeling between semantic representations of local regions, and multi-scale aggregation from local to global, which can alleviate the weak correlation problem for visual media analysis. In addition, we also investigate the local correlation research in more challenging tasks, i.e., dynamic visual media analysis on Embodied AI. In particular, multi-scale spatial and contextual modeling framework is proposed for visual navigation task, which can improve both the successful rate and efficiency.

Title：Cross-domain Image Reconstruction and Credible Identity Authentication
Abstract: As an important task for “Safe City” construction, city-level video surveillance has evolved from the first generation of “visible” and the second generation of “readable” to the third stage of “intelligible”. Due to the wide spatial distribution of city level cameras and large differences in their types and parameters, it is a major challenge to realize the “intelligible” city level video surveillance system. This lecture mainly introduces the recent progress on cross-domain image reconstruction and credible identity authentication technology, including (1) Behavior analysis (abnormal behavior detection, behavior location and recognition): complete semantic information extraction through multi-scale boundary sensitive network for temporal action localization; the differentiation of reconstruction quality of normal and abnormal data through the detection of temporal-spatial fusion features; (2) Cross-modality person re-identification: improving the feature modality invariance by measuring and constraining the modality differences between cross-modality person high-dimensional features; (3) Video object clarity (underlying vision): Improving the representation ability of inter-frame temporal dependence by joint priori information and motion invariance; (4) Cross-domain image synthesis (heterogeneous image generation and image stylization): Transforming the images from different modalities into unified modality to achieve information completion. (5) Cross-domain image recognition (heterogeneous face image recognition): Improving the interpretability and accuracy of cross-domain image synthesis and recognition through representation disentanglement learning. This research can provide a systematic solution for the intelligent analysis of network video streaming; (6) Credible identity authentication: here “credible” mainly refers to reliability and security. The algorithm is supposed to not only defend against external attacks (adversarial learning), but also protect private information.

Title: From Perceptual Quality to Cognitive Quality – Robust Image Analysis via Data Quality Assessment
Abstract: Data quality plays a critical role for robust image analysis. Unfortunately, due to various unforeseen noise and inevitable human error, our intelligent vision systems always suffer great challenge from poor data quality. On the one hand, the image data captured from the sensors may suffer different kinds of distortions, which causes domain shift and degrades the performance of image analysis model trained with pristine images. On the other hand, the manually annotated label data may also suffer incorrect labels, which misleads the supervised learning process. In this talk, I will introduce our recent efforts in conducting robust image analysis via data quality assessment. First, we present a relevance-aware incremental learning model to adapt to increasingly diverse image quality assessment tasks, which warns the intelligent vision system under image data distortion. Second, we introduce a graph reasoning based image quality enhancement method to alleviate the domain shift between the distorted image and the pristine image. Finally, we discuss a task-specific switchable loss for learning robust instance segmentation model from noisy label data.
