In this study, we theoretically identify three dimensions of expatriate competencies-ability, motivation, and opportunity seeking—for knowledge transfer. Integrating the ability-motivation-opportunity framework and the absorptive capacity perspective, we propose that expatriate competencies in knowledge transfer influence a subsidiary's performance through(More)
Automatic White Balance (AWB) is one of the important functions for digital cameras. The purpose is removing the color cast caused by the un-canonical illuminants where the image captured at. Images with color cast always lose the color contrast and variations, especially those with heavy color cast. For traditional white balance algorithms, the lost color(More)
Studies of contrast sensitivity of the human eyes show that logarithmic curves obey the Weber-Fechner law of just noticeable difference response in human perception. In this paper, we propose a local contrast enhancement algorithm with logarithm-based curves for both high dynamic and low dynamic images and this algorithm can adaptively change the curvature(More)
Goal of proposed algorithm is to enhance images like the digital camera photos or, better. Some enhancement filters process too excessive that makes image look unnatural. The paper proposes an algorithm to represent obviously the detailed textures and sharpen the overall image based on perceptual approach. Then the sharpened images are merged by the edge(More)
In this paper, we proposed a method to enhance global contrast of an image based on Average Luminance with Weighted Histogram Equalization (ALWHE) for Low Dynamic Range Images (LDRI). Automation of parameter selection can easily be done by iteratively using the proposed method. The purposed method overcomes the disadvantage of HE like luminance shifting and(More)

This study aims to investigate the interactive effects of task performance and impression management tactics on career outcomes from the socioanalytic perspective. Based on a survey of 195 employee-supervisor dyads from various industries in Taiwan, a hierarchical regression analysis revealed that (1) the relationship between task performance and a one-year(More)
The main objective of image enhancement is to increase quality and visibility. Since each block of an image has a given luminance, that is local information, a color enhancement method including local contrast enhancement, local sharpness enhancement and local color enhancement is proposed for improving the quality and visibility flow-exposure and(More)
Digital images are subject to a wide variety of distortions during image processing application, and it is necessary to develop objective image quality metric to evaluate the degradation automatically. Images are prepared for human eyes so that the assessment result must be consistent with human visual effect. Structure Similarity (SSIM), a well-known(More)
In this paper, we propose histogram modification and combine with Fuzzy C-means(FCM) to improve overall contrast. Over-enhancing and some artifact can be reduced effectively. In the various images the propose method can achieve adjustment level of enhancement via setting cluster C. By experiments the propose method can preserve good brightness and yield(More)
