UI layers merger: merging UI layers via visual learning and boundary prior Research Article

Yunnong CHEN, Yankun ZHEN, Chuning SHI, Jiazhi LI, Liuqing CHEN, Zejian LI, Lingyun SUN, Tingting ZHOU, Yanfang CHANG

Frontiers of Information Technology & Electronic Engineering 2023, Volume 24, Issue 3,   Pages 373-387 doi: 10.1631/FITEE.2200099

Abstract: With the fast-growing graphical user interface (GUI) development workload in the Internet industry, some work attempted to generate maintainable front-end code from GUI screenshots. It can be more suitable for using user interface (UI) design drafts that contain UI metadata. However, fragmented layers inevitably appear in the UI design drafts, which greatly reduces the quality of the generated code. None of the existing automated GUI techniques detects and merges the fragmented layers to improve the accessibility of generated code. In this paper, we propose UI layers merger (UILM), a vision-based method that can automatically detect and merge fragmented layers into UI components. Our UILM contains the merging area detector (MAD) and a layer merging algorithm. The MAD incorporates the boundary prior knowledge to accurately detect the boundaries of UI components. Then, the layer merging algorithm can search for the associated layers within the components' boundaries and merge them into a whole. We present a dynamic data augmentation approach to boost the performance of MAD. We also construct a large-scale UI dataset for training the MAD and testing the performance of UILM. Experimental results show that the proposed method outperforms the best baseline regarding merging area detection and achieves decent layer merging accuracy. A user study on a real application also confirms the effectiveness of our UILM.

Abstract:

To meet a growing demand for information processing, brain-inspired neuromorphic devices have been intensively studied in recent years. As an important type of neuromorphic device, have attracted strong attention. Among all the kinds of materials explored for the fabrication of , s (NCs) have become one of the preferred choices due to their excellent electronic and optical properties. In this review, we first introduce the research background of based on semiconductor NCs and briefly present the basic properties of semiconductor NCs. Recent developments in the field of based on semiconductor NCs are then discussed according to the materials employed in the active layers of the devices. Finally, we discuss existing problems and challenges of based on semiconductor NCs.

Texture branch network for chronic kidney disease screening based on ultrasound images Research Articles

Frontiers of Information Technology & Electronic Engineering 2020, Volume 21, Issue 8,   Pages 1119-1266 doi: 10.1631/FITEE.1900210

Abstract: (CKD) is a widespread renal disease throughout the world. Once it develops to the advanced stage, serious complications and high risk of death will follow. Hence, early screening is crucial for the treatment of CKD. Since ultrasonography has no side effects and enables radiologists to dynamically observe the morphology and pathological features of the kidney, it is commonly used for kidney examination. In this study, we propose a novel convolutional neural network (CNN) framework named the to screen CKD based on images. This introduces a texture branch into a typical CNN to extract and optimize texture features. The model can automatically generate texture features and deep features from input images, and use the fused information as the basis of classification. Furthermore, we train the base part of the network by means of , and conduct experiments on a dataset with 226 images. Experimental results demonstrate the effectiveness of the proposed approach, achieving an accuracy of 96.01% and a sensitivity of 99.44%.
