In contrast to fixed clock cycles in conventional design, the modified dynamic frequency counting loop dependents on the states with variable clock cycles. We also applied the LFSR fractional dithering technique to enhance the resolution of multiphase digitally controlled oscillator. A test chip for the proposed all-digital clock generator was fabricated in a standard 0.18µm CMOS technology, and the core area was 0.112mm2. The output frequency had a range of 113MHz~360MHz at 1.8V with RMS jitter 28ps at 359.78MHz/1.8V.","PeriodicalId":6765,"journal":{"name":"2019 International Symposium on Intelligent Signal Processing and Communication Systems (ISPACS)","volume":"81 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":"85500461","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}

The proposed method extends the effectiveness of Progressive Secret Sharing (PSS) into the Friendly Secret Sharing (FSS). The PSS produces a set of shared images in noisy-like form, while FSS generates shared images into more-visually-friendly appearance. The proposed method offers lossless ability in the recovery result of secret image. At the same time, it shows superiority compared to the former existing scheme in the secret sharing task.","PeriodicalId":6765,"journal":{"name":"2019 International Symposium on Intelligent Signal Processing and Communication Systems (ISPACS)","volume":"17 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":"83037249","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 several biometrics, human fingerprint has became one of the most popular biometrics traits. However, the manipulation of the fingerprint data rises the urgent needs of fingerprint data authentication to protect the digital content and ensure authenticity. In this paper, we propose a protection scheme to provide authenticity as well as integrity for individual fingerprint data. A well known reversible data embedding technique named different expansion (DE) is adopted to allow the exact recovery of the hashed fingerprint data with personal secret for authentication. Depending on the size of the data to be embedded, the proposed scheme is able to maintain low distortion over the source fingerprint data, hence maintaining its visual quality and original data structure.","PeriodicalId":6765,"journal":{"name":"2019 International Symposium on Intelligent Signal Processing and Communication Systems (ISPACS)","volume":"83 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":"86553851","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}

A conventional method based on MNMF separates an observed signal into a target signal and other distant sound sources. Unfortunately, MNMF often degrades the separation performance owing to the basis-sharing problem. Our penalized method forces the target basis to become different from the nontarget one. Experimental results show that the proposed method can improve the separation capability more than the conventional one.","PeriodicalId":6765,"journal":{"name":"2019 International Symposium on Intelligent Signal Processing and Communication Systems (ISPACS)","volume":"136 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":"76389911","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}

Long wavelength light is easily absorbed. Also, the light attenuation rate of blue and green component changes according to the water quality, thus, the white balance of images is lost. The attenuation of the light reduces colorfulness and contrast of images, furthermore, causes blurring. When photographing, the illumination becomes uneven for the subject, thus, brightness unevenness occurs in the acquired captured images. In this paper, an underwater image signal is converted to the ideal HSI color space and apply processing suitable for various deterioration factors to saturation and intensity independently.

Among them, IEEE 802.3ch is establishing a PHY layer standard to support In-Vehicle Network's gigabit Ethernet. Among the standardization issues of IEEE 802.3ch, there is an asymmetric data transfer issue. This is an issue to discuss how to cope when the differences in data transmission rates are different between up and down directions. In this paper, we propose a link speed switching method using auto-negotiation as a way to provide solutions to these issues. This has the advantage of preventing data loss when switching the link speed.
