In this study, we theoretically identify three dimensions of expatriate competenciesability, 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)
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)
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)
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)
Twenty-four microsatellite markers were developed for the Crested Serpent Eagle (Spilornis cheela hoya) composing a new marker set. The markers were tested on 61 Crested Serpent Eagle individuals. The number alleles ranged from 2 to 8 per locus (average = 3.8), and the effective number of alleles ranged from 1.13 to 6.07 (average = 2.34). In the new marker(More)
When capturing scene in a real world, traditional display devices would encounter a problem of representing high contrast. It is because the part in the dimmest region or in the brightest region is almost invisible. The causes of this invisible part can be ascribed to two limits-the brightness adaptation of eye and the architecture of display devices. To(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)
This study proposed a contrast enhancement algorithm. Some methods enhance images depending on only the global or the local information, therefore it would cause over-enhancement usually and make the image look unnatural. The proposed method enhances image based on the global and local information. For the global part, we proposed mapping curves to find the(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)
