Over-sketching Operation to Realize Geometrical and Topological Editing across Multiple Objects in Sketch-based CAD Interface

Autor: Teruyoshi Kaneko, Yoshiki Tanaka, Tomohiko Ito, Sato Saga

Publikováno v: IUI Companion

We developed a new general-purpose sketch-based interface for use in two-dimensional computer-aided design (CAD) systems. In this interface, a sketch-based editing operation is used to modify the geometry and topology of multiple geometric objects vi

An infinite-resolution grid snapping technique based on fuzzy theory

Autor: Tomohito Yoshikawa, Tomohiko Ito, Ten Watanabe, Sato Saga, Yuto Miwa, Takeshi Shibata

Publikováno v: Applied Soft Computing. 89:106112

In ordinary CAD systems with pointing devices, users input geometric objects by inputting their feature points one by one through pointing and dragging operations. Thus, each of the feature points is snapped into place interactively, and the geometri

PBLs signifies both problem-based learning and project-based learning; we clearly distinguish between the two types of PBLs. The former PBL involves finding ways to solve problems under unfavorable conditions. In the curriculum at our institute, prob

Anisotropic Dynamic-Morphological-Diffusion for Segmentation of Noisy Color Images

Autor: Sato Saga, Takehiro Harada, Junji Maeda, Yukinori Suzuki

Publikováno v: Journal of Advanced Computational Intelligence and Intelligent Informatics. 18:204-212

In this paper, we propose a modified anisotropic diffusion algorithm using the dynamicmorphological filtering as a new precise edge-preserving smoothing technique for an accurate segmentation of color images with heavy noise. We incorporate a dynamic

Snapping of Fuzzy Objects Using the Multi-Resolution Fuzzy Grid Snapping Technique

Autor: Masaki Sakurai, Sumudu Dematapitiya, Masatoshi Kawazoe, Sato Saga, Akira Nishikawa

Publikováno v: Journal of Information Processing. 17:47-58

In the present paper, we propose an automatic snapping method that aligns fuzzy objects in a multi-resolution grid system in order to improve the efficiency of sketch-based CAD systems. The sketch-based CAD system that we have previously realized suc

Vector quantization of images with variable block size

Autor: Kazuya Sasazaki, Yukinori Suzuki, Junji Maeda, Sato Saga

Publikováno v: Applied Soft Computing. 8:634-645

We proposed a vector quantization (VQ) with variable block size using local fractal dimensions (LFDs) of an image. A VQ with variable block size has so far been implemented using a quad tree (QT) decomposition algorithm. QT decomposition carries out

A Multi-Resolution Grid Snapping Technique Based on Fuzzy Theory

Autor: Qamar Uddin Khand, Sato Saga, Sumudu Dematapitiya, Junji Maeda

Publikováno v: IPSJ Digital Courier. 3:198-206

This paper presents a grid snapping technique, called multi-resolution fuzzy grid snapping (MFGS), that enables automatic mouse cursor snapping for a multi-resolution grid system. Quick and frequent switching between high- and low-resolution grid sna
