This evolution is evident in ongoing efforts towards app feature recommendation, reflecting a concerted endeavor to enhance user experience and satisfaction. However, the increasing complexity in app functionalities, particularly within the Graphical User Interface (GUI), presents significant challenges for users to find their desired functions. Further, by conducting an online survey, we found that 85% of participants encounter difficulties in locating desired functionalities within apps, which can lead to frustration and even app abandonment. To tackle this challenge, we propose an approach that leverages GUI screenshots and layout files to analyze app functions. Our approach involves vectorizing app functions based on user search times and function descriptions, followed by personalized analysis, initial difficulty assessment, and refinement through clustering techniques. To evaluate our method, we carry out experiments on 49 apps across 8 categories demonstrate the effectiveness of our approach. Our approach achieves an accuracy rate of 91.29% on average in identifying hard-to-find functions and observes significant performance improvements after reducing random data.

However, there has been a noticeable absence of comprehensive reviews that can offer detailed classification, analysis, and comparison of the rich existing methods. To fill this gap, we provide an overview of ML methods applied in ACL and meniscus MRI analysis between 2013 and 2024. Sixty-seven papers covering tasks such as classification, segmentation, localization, and prediction are investigated and classified from the perspective of the ML method. For conventional ML methods, we summarized four kinds of handcrafted MRI features related to the ACL and meniscus, along with corresponding ML models. Meanwhile, we categorize the deep learning methods into 11 types according to the network structures for various tasks. Based on the categorization, we further compare the main methods and analyze the critical factors for existing successful models. Current trends and future directions in this field are also elaborately discussed.

To solve this problem, we first construct a real-world NightHDR video dataset, which contains 57 LDR-HDR video pairs captured under night scenes in both raw and sRGB formats, where the LDR frame includes short and long exposures. Different from previous alternating exposure based or frame based HDR video reconstruction, we turn to staggered HDR reconstruction, which is more applicable in real scenarios.

This study investigates the impact of light distribution in LED displays on visual performance and energy consumption. Through software simulations and experimental measurements, we established a quantitative model linking beam angle with the maximum viewing angle and energy consumption of displays. The results show that a display with a 60° beam angle consumes only half the energy of a display with a 120° beam angle, while achieving 89% of the latter’s maximum viewing angle.

Our approach is designed to handle different types of tumors, encompassing MRI brain tumor segmentation, three breast tumor ultrasound segmentation tasks, and cholorectal polyp segmentation from the Kvasir dataset. EDRNet incorporates advanced architectural features such as Enhanced Residual Dilated Blocks and a Deep Residual Network (DRNet), alongside an EfficientNet-based encoder, optimizing the extraction and processing of image features. A key innovation in our model is the integration of Spatial Channel Fusion Attention, with the DRNet which combines global and local feature extractors using an attention feature fusion module. Our modified Attention Feature Fusion Module (AFFM) plays a crucial role in integrating local features (lc), fused features (fuse), and global features (gf) to produce a rich, multi-scale representation for improved segmentation performance at decoder part. Furthermore, we have used the transfer learning based approach to train single model for the multiple cancer datasets with combine loss functions to efficiently train the neural networks. Specifically, in the MRI and breast cancer datasets, EDRNet has demonstrated good capability in properly segmenting all types of brain tumors with precise details, whether located on the left or right side of the brain. This design choice significantly enhances the model’s ability to differentiate low and high level features and boundaries in medical images, crucial for accurate segmentation. Quantitative evaluations demonstrate that EDRNet sets new benchmarks on all considered datasets. Notably, improvements in Intersection over Union (IoU) were recorded as a 9 % increase for the MRI brain tumor segmentation, a substantial 4% enhancement for breast cancer segmentation datasets, and a 1.5% improvement in cholorectal polyp segmentation on the Kvasir dataset.

These methods usually extract features from different receptive fields through downsampling operations, and then enhance underwater images through upsampling operations. However, these operations of downsampling and upsampling inevitably disrupt the relations of neighboring pixels in raw underwater images, leading to the loss of image details. Given this, a multi-stream feature fusion network, dubbed MSFFNet, is proposed to enrich details, correct colors, and enhance contrast of degraded underwater images. In MSFFNet, the multi-stream feature estimation block is carefully constructed, which separately takes original resolution feature maps and low-resolution feature maps as inputs. The multi-stream feature estimation block proficiently preserves the details information of the original underwater image while extracting high-level features. Besides, a coordinate residual block is designed to emphasize valuable features and suppress noises based on position knowledge. A local–global feature fusion block is presented for selectively fusing the complementary multi-scale features. Finally, extensive comparative experiments on real underwater images and synthetic underwater images demonstrate that the proposed MSFFNet has superior performance on underwater image enhancement tasks.</div></div>","PeriodicalId":50570,"journal":{"name":"Displays","volume":"88 ","pages":"Article 103023"},"PeriodicalIF":3.7,"publicationDate":"2025-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143705699","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nevertheless, there is limited research investigating the impacts of vibration directions and touch methods on human tactile perceptions. This study aims to address this research gap by exploring the impacts of both normal and lateral vibration directions, as well as passive and active touch methods, on human tactile perceptions. Two tactile perception experiments were conducted at frequencies of 150 Hz, 200 Hz, 250 Hz, and 300 Hz. The experimental results show that for the same displacements, lateral vibrations are significantly more perceivable than normal vibrations for both passive and active touches, except at 150 Hz for passive touch. However, the normal vibrotactile perceivable thresholds are significantly lower than those for lateral vibrations for both passive and active methods. This study also surprisingly found that the most sensitive frequency for lateral vibration is around 150 Hz and 200 Hz, which is about 50–100 Hz lower than that for normal vibration. These findings can help us understand how different vibration directions and touch methods affect human tactile perception, which are important factors in designing tactile human–computer interfaces.</div></div>","PeriodicalId":50570,"journal":{"name":"Displays","volume":"88 ","pages":"Article 103036"},"PeriodicalIF":3.7,"publicationDate":"2025-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143685187","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
