Indoor thermal comfort is one of an important factor affecting the performance of our measurement. We measured the parameters of indoor chamber volume, temperature, humidity, heat and other human's subjective feelings of comfort. On the other hand, we also consider of energy issues, by use of genetic algorithms to achieve an optimal balance between thermal comfort and energy consumption, to aim of...
Internet of things combine big data extends for many applications, including intelligent cities, smart home, intelligent transportation or wearable devices. Internet of things combine big data extends for many applications, including intelligent cities, smart home, intelligent transportation or wearable devices. There is little analysis for individual vehicle or group of the vehicle. Design a monitoring...
Mobile technology and Applications are growing rapidly which provide another service way. In the area of Engineering in Medicine and Biology is a positively affected by new technology and availability. We proposed a prototype of medical image (DICOM [6]) retrieval Application with Quick Response Code (QR-Code) [7] authentication based on Android operating system, which can help personal clinics and...
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 detail.
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 information of original image. The experimental...
The ultimate goal of realistic graphics is the creation of images that provoke the same responses that a viewer would have to a real scene. In the field of computer graphics, one related key problem is the issue of displaying radiant intensities in a meaningful way. The paper proposed an efficient local contrast enhancement algorithm by histogram equalization and histogram stretching method. The algorithm...
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 overcome this problem, contrast enhancement...
Digital cameras that gradually replace conventional cameras store photographs in digital format. As a result, captured images can be more easily processed. Consequently the quality of image is more important. In this paper, we present an overview of image quality attributes of different contrast enhancement in gray level images. Moreover, we present results of analysis for some contrast enhancement...
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 washed-out looking. We present experimental...
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 with local information. We also define two...
