Implications for cumulative and prolonged clinical improvement induced by cross‐linked hyaluronic acid: An in vivo biochemical/microscopic study in humans

Frank Wang, Thy Thy Do, Noah Smith, Jeffrey S. Orringer, more

Experimental Dermatology > 33 > 1 > n/a - n/a

In photoaged human skin, type I collagen fragmentation impairs dermal extracellular matrix (ECM) integrity, resulting in collapsed/contracted fibroblasts with reduced type I procollagen synthesis. Injections of cross‐linked hyaluronic acid (CL‐HA) reverse these deleterious changes. To investigate the time course and effects of biochemical changes induced by injected CL‐HA, particularly whether fibroblast...

Carli P. Whittington, Jasmine S. Saleh, Eric Schadler, Carole Bitar, more

Journal of Cutaneous Pathology > 50 > 11 > 942 - 946

Malakoplakia is a rare chronic inflammatory condition that most commonly involves the urogenital tract. Cutaneous malakoplakia is extremely rare and many patients diagnosed with skin involvement are immunosuppressed. While the clinical presentation of cutaneous malakoplakia is variable, the histopathologic features are quite distinct and include sheets of closely packed dermal histiocytes with foamy‐appearing...

Management Risk Incentives and the Readability of Corporate Disclosures

Bidisha Chakrabarty, Ananth Seetharaman, Zane Swanson, Xu (Frank) Wang

Financial Management > 47 > 3 > 583 - 616

Managers with higher risk incentives (greater options vega) issue less readable disclosures. Firms in the top quartile of vega file annual reports that are about 15.4% more voluminous than those in the bottom quartile. The effect of vega on obfuscation remains after controlling for firm risk, operating complexities, accounting and auditor choices, chief executive officer changes, and an exogenous...

Gallbladder mucosal lesions associated with high biliary amylase irrespective of pancreaticobiliary maljunction

Jason Free, Frank Wang, Nick Williams, Justin S. Gundara, more

ANZ Journal of Surgery > 88 > 6 > E517 - E521

Background Previous studies have focused on the presence of reflux in selected cohorts with pancreaticobiliary maljunction (PBM), but little is known regarding the wider incidence of occult reflux and associated mucosal changes. We aimed to correlate gallbladder mucosal abnormalities with objective evidence of PBM and occult pancreaticobiliary reflux (PBR) in an Australian population undergoing cholecystectomy...

Edge-Preserving Depth Map Upsampling by Joint Trilateral Filter

Kai-Han Lo, Yu-Chiang Frank Wang, Kai-Lung Hua

IEEE Transactions on Cybernetics > 2018 > 48 > 1 > 371 - 384

Compared to the color images, their associated depth images captured by the RGB-D sensors are typically with lower resolution. The task of depth map super-resolution (SR) aims at increasing the resolution of the range data by utilizing the high-resolution (HR) color image, while the details of the depth information are to be properly preserved. In this paper, we present a joint trilateral filtering...

No More Discrimination: Cross City Adaptation of Road Scene Segmenters

Yi-Hsin Chen, Wei-Yu Chen, Yu-Ting Chen, Bo-Cheng Tsai, more

2017 IEEE International Conference on Computer Vision (ICCV) > 2011 - 2020

2017 IEEE International Conference on Computer Vision (ICCV)

Despite the recent success of deep-learning based semantic segmentation, deploying a pre-trained road scene segmenter to a city whose images are not presented in the training set would not achieve satisfactory performance due to dataset biases. Instead of collecting a large number of annotated images of each city of interest to train or refine the segmenter, we propose an unsupervised learning approach...

Domain-Adaptive generative adversarial networks for sketch-to-photo inversion

Yen-Cheng Liu, Wei-Chen Chiu, Sheng-De Wang, Yu-Chiang Frank Wang

2017 IEEE 27th International Workshop on Machine Learning for Signal Processing (MLSP) > 1 - 6

2017 IEEE 27th International Workshop on Machine Learning for Signal Processing (MLSP)

Generating photo-realistic images from multiple style sketches is one of challenging tasks in image synthesis with important applications such as facial composite for suspects. While machine learning techniques have been applied for solving this problem, the requirement of collecting sketch and face photo image pairs would limit the use of the learned model for rendering sketches of different styles...

Learning guided convolutional neural networks for cross-resolution face recognition

Tzu-Chien Fu, Wei-Chen Chiu, Yu-Chiang Frank Wang

2017 IEEE 27th International Workshop on Machine Learning for Signal Processing (MLSP) > 1 - 5

2017 IEEE 27th International Workshop on Machine Learning for Signal Processing (MLSP)

Cross-resolution face recognition tackles the problem of matching face images with different resolutions. Although state-of-the-art convolutional neural network (CNN) based methods have reported promising performances on standard face recognition problems, such models cannot sufficiently describe images with resolution different from those seen during training, and thus cannot solve the above task...

Enhanced canonical correlation analysis with local density for cross-domain visual classification

Wei-Jen Ko, Jheng-Ying Yu, Wei-Yu Chen, Yu-Chiang Frank Wang

2017 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP) > 1757 - 1761

2017 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP)

Real-world visual classification tasks typically need to deal with data observed from different domains. Inspired by canonical correlation analysis (CCA), we propose an enhanced CCA with local density for associating and recognizing cross-domain data. In addition to maximizing the correlation of the projected cross-domain data, our CCA model further exploits the local density information observed...

Learning Grassmann manifolds for object state discovery

Hao-Wei Lee, Chia-Po Wei, Yu-Chiang Frank Wang

2017 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP) > 1223 - 1227

2017 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP)

In this paper, we advocate the use of Grassmann manifolds for discovering object images in different states (e.g., unripe, peeled, etc.). We propose a novel dictionary learning algorithm, which derives the subspaces on a Grassmann manifold for describing each object state. By our introduced geodesic-flow constraint, our Grassmann manifold exhibits excellent capabilities in relating objects in distinct...

Partial image blur detection and segmentation from a single snapshot

Te-Li Wang, Kuan-Yun Lee, Yu-Chiang Frank Wang

2017 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP) > 1907 - 1911

2017 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP)

In this paper, we address the problem of detecting and segmenting partial image blur from a single input image. Instead of assuming particular image priors or requiring additional user annotation, we propose a novel learning framework which jointly solves the tasks of blur kernel estimation and image blur segmentation, so that partial image blur can be automatically separated from the remaining parts...

Bayesian Inventory Management with Potential Change‐Points in Demand

Zhe (Frank) Wang, Adam J. Mersereau

Production and Operations Management > 26 > 2 > 341 - 359

We consider the inventory management problem of a firm reacting to potential change points in demand, which we define as known epochs at which the demand distribution may (or may not) abruptly change. Motivating examples include global news events (e.g., the 9/11 terrorist attacks), local events (e.g., the opening of a nearby attraction), or internal events (e.g., a product redesign). In the periods...

Unsupervised Domain Adaptation With Label and Structural Consistency

Cheng-An Hou, Yao-Hung Hubert Tsai, Yi-Ren Yeh, Yu-Chiang Frank Wang

IEEE Transactions on Image Processing > 2016 > 25 > 12 > 5552 - 5562

Unsupervised domain adaptation deals with scenarios in which labeled data are available in the source domain, but only unlabeled data can be observed in the target domain. Since the classifiers trained by source-domain data would not be expected to generalize well in the target domain, how to transfer the label information from source to target-domain data is a challenging task. A common technique...
