Color image segmentation method using watershed algorithm and contour information
Ayako Shiji,Nozomu Hamada +1 more
TL;DR: In this paper, a segmentation method of color images with being rid of oversegmentation is proposed, which uses not only the pixel's property but also the information of regions' contour.
Journal ArticleDOI
System reduction by continued-fraction expansion about s=jωi
TL;DR: In this paper, a method of system reduction using the continued fraction expansion about arbitrary points on the real frequency axis is proposed, which gives a good approximation and the procedure is suitable for digital computation.
Journal Article
Voice Activity Detection with Array Signal Processing in the Wavelet Domain
Yusuke Hioka,Nozomu Hamada +1 more
TL;DR: In this paper, a novel VAD method with array signal processing on wavelet domain is proposed, in which the time, frequency and space information in the speech signal is utilized to separate interferences.
Proceedings ArticleDOI
Feature edge extraction from 3D triangular meshes using a thinning algorithm
Masaru Nomura,Nozomu Hamada +1 more
TL;DR: It is shown that the proposed method can extract appropriate feature edges from 3D meshes using a thinning algorithm, which is used in 2D binary image processing.
