Most learning-based low-light image enhancement methods typically suffer from two problems. First, they require a large amount of paired data for training, which are difficult to acquire in most cases. Second, the process enhancement, noise is be removed and may even amplified. In other words, performing denoising illumination at same time difficult. As an alternative supervised learning strategies that use data, as presented previous work, this paper presents mixed-attention guided...

Due to the lack of large-scale labeled Thermal InfraRed (TIR) training datasets, most existing TIR trackers are trained directly on RGB datasets. However, tracking methods datasets suffer a significant drop-off in data, due domain shift issue. To address this issue, we propose Progressive Domain Adaptation framework for (PDAT), which can effectively transfer knowledge from without requiring large amount data. The consists an Adversarial-based Global module and Clustering-based Subdomain...

Sour porridge, a fermented food from the Guangxi Zhuang Autonomous Region of China, contains an abundance lactic acid bacteria and has high nutritional value. In this study, strain Schleiferilactobacillus harbinensis GX0002947 was isolated naturally sour porridge Fusui County, Chongzuo City, China. The highly effective in fermentation porridge. It found that S. showed good bile salt resistance at pH 3.5, concentration 0.3 g/100 mL, artificial gastrointestinal fluids, bacterial population...

Background and Purpose— Permeability surface (PS) on computed tomographic perfusion reflects blood–brain barrier permeability is related to hemorrhagic transformation (HT). HT of deep middle cerebral artery (MCA) territory can occur after recanalization proximal large-vessel occlusion. We aimed determine the relationship between PS MCA territory. Methods— retrospectively reviewed 70 consecutive acute ischemic stroke patients presenting with occlusion distal internal carotid or M1 segment...

Purpose: The relationship of clinical results and survival analysis operative patients with petroclival meningioma (PCM) was studied. Patients methods: Data from a total 176 PCM receiving surgical resection were retrospectively collected. Follow-up conducted through outpatient review by reexamination telephone calls letters. Clinical outcomes, survival, Karnofsky Performance Scale (KPS) data analyzed. Results: Seventy-two percent (127/176) received only surgery, 8.5% (15/176) surgery...

The identification of microorganisms with excellent flocculants-producing capability and optimization the fermentation process are necessary for wide-scale application bioflocculants. Therefore, we isolated identified a highly efficient flocculation performance strain Stenotrophomonas pavanii GXUN74707 from sludge. optimal conditions S. was in medium glucose urea as carbon nitrogen sources, respectively, at pH 7.0 36 h, which treatment kaolin suspension 0.5 mL broth resulted rate 99.0%....

A visual tracing model based on Risley prisms is proposed in this paper. Combined with the boresight adjusting technology and detection technology, a new system established. Placing front of camera, field view camera can be dynamically adjusted so that imageable area expanded greatly. Two real-time strategies for dynamic targets are proposed, which effectively avoid problems target loss tracking instability. The deviations between reference trajectory generated by manipulator actual detected...

The existing machine vision systems cannot efficiently detect white contaminants in cotton under the illumination of visible lights, because their color is same or very close. To solve problem, this article proposes an imaging method based on line lasers. Under a laser, and showed differences optical characteristic surface. Then, according to features intensity reflected lights distribution fluff around surfaces images, example algorithm for identification from was suggested. experimental...

We identified cancer stem cell (CSC)-enriched populations from murine melanoma D5 syngeneic to C57BL/6 mice and the squamous SCC7 C3H using ALDEFLUOR/ALDH as a marker, tested their immunogenicity lysate source of antigens pulse dendritic cells (DCs). DCs pulsed with ALDHhigh CSC lysates induced significantly higher protective antitumor immunity than unsorted whole tumor in both models lung metastasis setting s.c. growth setting, respectively. This phenomenon was due vaccine-induced humoral...

We analyzed bronchopulmonary carcinoid tumor (BPC) patients receiving resection from the Surveillance, Epidemiology, and End Results (SEER) database to identify predictive factors of their survival. Then, we developed validated nomograms predict overall survival (OS) cancer-specific (CSS) in BPC patients.BPC registered SEER were included. They divided into a training set an internal validation (7:3). our center included as external set. Independent prognostic identified by Cox regression...

In this paper, a novel algorithm in the contourlet domain is presented for segmenting lumbar vertebra CT image. Firstly we apply transform to image, use its multiscale and multidirectional characteristics get coefficients that they can effectively capture contours of an image depict them sparsely. Secondly, C-Means clustering applied derive edge information from coefficients. Experimental results are encouraging, which illustrate effectiveness algorithm. Compared with wavelet-based method,...

This study was performed to investigate the association of peripheral T lymphocyte subsets with disseminated infection (DI) by

In non-Manhattan geometry layout extraction, polygon to trapezoid decomposition is an indispensable step. Its efficiency and the organization of generated trapezoids significantly affect performance extractors. We present a new algorithm used in our extractor iLEX. The concept edge pair scanline interval are introduced provide improved over conventional algorithms. Definitions for corner stitches provided as well integrated algorithms on stitching generated. Complexity analysis shows that...

There is a significant difference in correlated color temperature between deep-space environmental light sources and that on the ground. The lack of accurate calibration parameters for cameras can lead to errors collected scientific image data, resulting failure tasks. Thus it vital significance white balance deep-space-exploration cameras. However, traditional white-balance methods have certain limitations. generalization ability correction matrix insufficient, ground poor on-orbit...

Due to the lack of large-scale labeled Thermal InfraRed (TIR) training datasets, most existing TIR trackers are trained directly on RGB datasets. However, tracking methods datasets suffer a significant drop-off in data due domain shift issue. To this end, work, we propose Progressive Domain Adaptation framework for Tracking (PDAT), which transfers useful knowledge learned from tracking. The makes full use without requiring time-consuming and labor-intensive labeling data. Specifically, first...
