Although the hue component can not be processed, it can be used for color image processing. However, the hue component has not been used for color image processing until now. It is already known that saturation components work effectively in color image enhancement. Therefore, in this paper, we define the hue-saturation gradient which is a gradient combining the saturation gradient and the hue gradient. The differential hue-saturation histogram equalization with variable enhancement degree (DHSHEwVED) is proposed. The proposed method can emphasize both intensity and saturation. The proposed method has two parameters, which can be used to adjust the contrast and colorfulness independently. We shows the effectiveness of proposed method from image processing results.","PeriodicalId":6765,"journal":{"name":"2019 International Symposium on Intelligent Signal Processing and Communication Systems (ISPACS)","volume":"5 1","pages":"1-2"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87994469","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among different methods, clock mesh provides high robustness to process, voltage, and temperature (PVT) variations due to redundant paths. However, the mesh structure suffers from high power dissipation. By contrast, conventional clock tree structure is commonly used due to low power consumption, less routing resource usage. Nevertheless, a tree-based network is highly sensitive to PVT variations. In this paper, we propose to use the hybrid structure that combines tree-based and mesh-based structures for power and skew trade-off methodology. Experimental results suggest that hybrid-structured clock network can minimize the total capacitance under skew constrains.","PeriodicalId":6765,"journal":{"name":"2019 International Symposium on Intelligent Signal Processing and Communication Systems (ISPACS)","volume":"29 1","pages":"1-2"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74557339","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the method, a picture of traffic light is initially assumed to extract and type of traffic light are first classified into man figure, color and numerical characters by some classification tools such as signature. In man figure case, color and man gesture are classified and both information are decided base on Fuzzy logic. In the case of numerical characters, they are first enhanced and then classified by a classifier.

Although CNNs are able to learn important patterns on raw images, images may contain unpredictable noise that can negatively influence the convolutional stage. Feature extraction cannot always accurately capture the desired features based solely on the input image, but including extra information could improve the result. This paper proposes a fusion input design to generate an additional feature that a CNN can use to provide extra ROI information. Whether a model can utilize the additional information is a determining factor that affects the performance improvement. The proposed method is tested on two public datasets with different structural designs.
