Abstract

Frame selection is a fundamental issue in video action recognition. It aims to minimize temporal redundancy and reduce computational cost. Current frame sampling strategies either rely on US based on motion, lacking emphasis on discriminative frames, or employ complex learning models or additional modal information, compromising generalizability. To address these challenges, this paper presents an adaptive frame selection strategy. It filters redundant frames through motion information and models relationships between each frame and others, thereby predicting the significance of each frame. This strategy combines the advantages of motion prior information and supervised learning. During training, frame importance-related constraints are integrated, guiding frames selection with strong discriminative features as inputs for the action recognition network. This frame selection method is integrated with backbone network structures such as TDN, GCTDN, AIM, and tested on three action datasets, Diving-48, UCF101 and HMDB51. The improvement on action recognition achieved is 4.4% on the Diving-48 dataset, 1.9% on the UCF101 dataset and 2.3% on HMDB51 dataset. Experimental results demonstrate that our selection strategy can be integrated with state-of-the-art action recognition models, leading to improved recognition performance.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
