Early works in video object detection focused on detecting and recognizing the scene and objects shown in a representative key-frame of a video shot, thus the temporal information of video s isobjectlost [3,4]. Recently, semantic-based video analysis tend to model a video clip as a ed graph whose nodes are high-level video objects performing Object detection in videos involves verifying the presence of an object in image sequences and possibly locating it precisely for recognition. Object tracking is to monitor an object's spatial and temporal changes during a video sequence, including its presence, position, size, shape, etc SELSA: Sequence Level Semantics Aggregation for Video Object Detection. faster rcnn为backbone,用两个selsa模块(其实就是self-attention)融合多帧训练时候的proposal特征,达到Spectral Clustering的效果

Dual Semantic Fusion Network for Video Object Detection

detect complete salient objects in static images, especially in complicated scenarios. Conventional saliency detection methods [2], [27], [28] usually design hand-crafted low-level features and heuristic priors, which are difficult to represent semantic objects and scenes. Recent advances on saliency detection mainly benefi support semantic search of the video objects. Semantic information extracted from a video object not only conveys information about that video object, but at the same time, it becomes semantic carrier for the next video object. In the real world, all video objects are logically related. To represent the complete semantics of the video your question is a bit of a fundamental one: visual short term tracking or object detection. Well, both will struggle when an object is super fast: the object can be blurry (large appearance change for a tracker or object detector) or change direction fast (and violate priors on motion) Summary of segmentation and object detection. Image under CC BY 4.0 from the Deep Learning Lecture. We can use object detectors and implement them as a sequence of region proposals and classification. Then this leads essentially to the family of RCNN-type of networks. Alternatively, you can go to single-shot detectors Abstract. Extending state-of-the-art object detectors from image to video is challenging. The accuracy of detection suffers from degenerated object appearances in videos, \eg, motion blur, video defocus, rare poses, etc. Existing work attempts to exploit temporal information on box level, but such methods are not trained end-to-end.We present flow-guided feature aggregation, an accurate and.

Video Salient Object Detection Using Spatiotemporal Deep Features have limitation in capturing the semantic concept of objects. Accordingly, these methods often fail when the salient object frame, the block-based CNN works on a sequence of frames of a video. compute deep features [25] or pooling a pixel-level featur recent success of object detection and instance segmentation using deep neural networks, Kalogeiton et al. [11] proposed an actor-action detection network on single frames in video, then applied SharpMask [17] to generate actor-action semantic segmentation. This approach is one of two-stage re nement, whereb nating between different objects. An object thus corresponds to a semantic topic within a video sequence and the object is tracked as a new topic that evolves over time and eventually disappears. We employ a Dirichlet Process Mixture Model (DPMM) to dynamically cluster detection responses into sets of objects an explicit semantic notion of video objects. Such an integra-tion with object recognition and segmentation not only facil-itates a holistic object model, but also provide a middle-level geometric representations for delineating semantic objects.
