An image texture was defined in terms of pixel intensities and directionality. However, most the current representation methods did not consider two key factors simultaneously. To effectively capture directional intensity information texture, this paper, we propose a novel robust local descriptor, named locally extremal pattern (LDEP), for classification. It extracts difference count (DLDCP) being made up DLDCP odd positions even to express area first place. Furthermore, acquire extremum...
Background: Postoperative poor sleep quality and decreased gastrointestinal motility function are common clinical problems. This study investigated the effects of dexmedetomidine (DEX) combined with sufentanil for patient-controlled analgesia (PCA) on postoperative after surgery in patients colorectal cancer. Methods: Patients undergoing cancer were randomly divided into three groups, DEX 0, 200, or 400 μg, each 150 μg PCA immediately surgery. The primary outcome was first 7 days based...
Many representation methods were built for gray image textures. However, they are not effective color textures in general. To alleviate this problem, paper we propose a novel Compact Interchannel Sampling Difference Descriptor (CISDD) texture classification. In particular, considering sampling-based method can capture more directional information, first use heavy-tailed distribution, t-distribution to generate sample points the patch calculate micro-block difference. Then model interchannel...
In practical applications, it is urgent to develop lightweight, fast, and accurate face detectors. Although the performance of detection has made tremendous progress with rapid development deep learning, they still struggle meet requirements both efficiency effectiveness. This because current detectors either use large networks or cumbersome processes oriented for accuracy but leading heavy model complexity slow inference speed various simple designs greatly sacrificing not actually...
Prophylactic pharmacotherapy for health care in patients with high risk of cardiac arrest (CA) is an elusive and less explored strategy. Melatonin has possibilities used as a daily nutraceutical to trigger the cellular adaptation. We sought find effects long-term prophylactic supplement melatonin on victim CA. Rats were divided into sham, CA, + CA (Mel CA) groups. The rats Mel group received IP injection 100 mg/kg 14 days. was induced by 8 min asphyxia followed manual cardiopulmonary...
The performance of face detection has achieved great progress with the rapid development convolutional neural network. However, detecting faces a wide range scales is still challenging and crucial problem, especially for small faces. We focus on designing strong network architecture, aiming at generating high-quality feature representation to handle multiscale problem. Specifically, we conduct an in-depth study three aspects, including fusion, attention mechanism, receptive field, then...
Dense micro-block difference (DMD) has achieved good performance in gray texture representation and classification. However, its is not satisfactory when representing color texture. To alleviate this problem, we propose a novel method based on Completed Extremely Nonnegative DMD (CEN-DMD) paper. In particular, first use to model interchannel features of images. Considering that negative value meaningless digital image, perform nonnegative operation during the process. Due maximum patch...
Objective To analyze the clinical characteristics, diagnosis, differential diagnosis and treatment of gastrointestinal schwannoma. Methods Clinical data 3 patients with schwannoma were collected retrospectively analyzed. Results Gastrointestinal bleeding or melena, anemia epigastric pain most common presenting symptoms. The symptoms, physical signs auxiliary examinations (such as X-ray, ultrasonography endoscopy) had no value in differentiation. In all definite was achieved only...

The performance of face detection has made great progress with the rapid development deep learning. However, small faces only contain an extremely limited number pixels, which makes them suffer from poor feature representation and low-quality positive anchors. These problems make still a highly challenging task In this paper, we conduct in-depth study perspective learning anchor matching present small-scale aware detector (SFDet), can accurately detect faces. Specifically, first propose...
Color texture representation is an important step in the task of classification. Shortest paths was used to extract color features from RGB and HSV spaces. In this paper, we propose use shortest HSI space build a for particular, two undirected graphs are model H channel S I channels respectively order represent image. Moreover, constructed by using four pairs pixels according different scales directions Experimental results on colored Brodatz USPTex databases reveal that our proposed method...
Introduction: Prophylactic pharmacotherapy for health care in reducing death after cardiac arrest (CA) is an elusive and less explored strategy. Melatonin, a natural product contributing to sleep, was elevated upon arousal from torpor hibernating mammals, which increased survival blood return reduced reperfusion injury. In this study, we sought find the effects of long-term daily prophylactic supplement with melatonin as medicine on victim CA. Methods: SD rats, 240-340 g, were used study....
