Meanwhile, due to the lack of early large-scale video HOI datasets and the high computational cost of spatial-temporal HOI model training, recent exploratory studies mostly follow a two-stage paradigm, but independent object detection and interaction recognition still suffer from computational redundancy and independent optimization. Therefore, inspired by the one-stage interaction point detection framework, a one-stage spatial-temporal HOI detection baseline is proposed in this paper, in which the short-term local motion features and long-term temporal context features are obtained by the proposed temporal differential excitation module (TDEM) and DLA-TSM backbone. Complementary visual features between multiple clips are then extracted by multi-feature fusion and fed into the parallel detection branches.

However, due to the dependency on the adjacent or distant decoded features, existing methods require an inefficient serial processing structure, which significantly limits its practicability. Instead of pursuing computationally expensive entropy estimation, we propose to reduce the spatial redundancy via the channel-wise scale adaptive latent representation learning, whose entropy coding is spatially context-free and parallelizable. Specifically, the proposed encoder adaptively determines the scale of the latent features via a learnable binary mask, which is optimized with the RD cost. In this way, lower-scale latent representation will be allocated to the channels with higher spatial redundancy, which consumes fewer bits and vice versa. The downscaled latent features could be well recovered with a lightweight inter-channel upconversion module in the decoder. To compensate for the entropy estimation performance degradation, we further develop an inter-scale hyperprior entropy model, which supports the high efficiency parallel encoding/decoding within each scale of the latent features. Extensive experiments are conducted to illustrate the efficacy of the proposed method. Our method achieves bitrate savings of 18.23%, 19.36%, and 27.04% over HEVC Intra, along with decoding speeds that are 46 times, 48 times, and 51 times faster than the baseline method on the Kodak, Tecnick, and CLIC datasets, respectively.</div></div>","PeriodicalId":49521,"journal":{"name":"Signal Processing-Image Communication","volume":"130 ","pages":"Article 117227"},"PeriodicalIF":3.4,"publicationDate":"2024-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142579042","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we introduce BMINet, an innovative scene text detection approach based on boundary fitting, paired with a double-supervised scene text recognition method that incorporates text region correction. The BMINet framework is primarily structured around a boundary fitting module and a multi-scale fusion module. The boundary fitting module samples a specific number of control points equidistantly along the predicted boundary and adjusts their positions to better align the detection box with the text shape. The multi-scale fusion module integrates information from multi-scale feature maps to expand the network’s receptive field. The double-supervised scene text recognition method, incorporating text region correction, integrates the image processing modules for rotating rectangle boxes and binary image segmentation. Additionally, it introduces a correction network to refine text region boundaries. This method integrates recognition techniques based on CTC loss and attention mechanisms, emphasizing texture details and contextual dependencies in text images to enhance network performance through dual supervision.

In this paper, new Full Reference (FR) techniques, providing estimates linearly correlated with human scores without using calibration are introduced. We show that on natural images, application of estimation theory and psychophysical principles to images degraded by Gaussian blur leads to a so-called canonical IQA method, whose estimates are linearly correlated to both the subjective scores and the viewing distance. Then, we show that any mainstream IQA methods can be reconducted to the canonical method by converting its metric based on a unique specimen image. The proposed scheme is extended to wide classes of degraded images, e.g. noisy and compressed images. The resulting calibration-free FR IQA methods allows for comparability and interoperability across different imaging systems and on different viewing distances. A comparison of their statistical performance with respect to state-of-the-art calibration prone methods is finally provided, showing that the presented model is a valid alternative to the final 5-parameter calibration step of IQA methods, and the two parameters of the model have a clear operational meaning and are simply determined in practical applications.
