This paper proposes an algorithm for solving subsets of typical (canonical) jigsaw puzzles. This algorithm combines shape and image matching with a cyclic ‘‘growth’’ process that tries to place pieces in their correct positions. First, the jigsaw pieces are extracted from the input image. Then, the corner points of the jigsaw pieces are detected. Next, piece classification and recognition are p...

This article presents an evaluation plan for Jigsaw– an interactive visualization system to support investigative analysis. Jigsaw provides multiple views of a document collection and the individual entities within those documents, with a particular focus on exposing connections between entities. We describe how we plan to evaluate Jigsaw on different levels: general usability first, then focus...

This project involved the use of two small, closely matched non-majors introductory biology classes to test the use of the Jigsaw method of teaching vs. a passive, instructor-oriented model of teaching. In this study, the Jigsaw method was used as a jumping off point for the teaching-learning of the material. Students were to learn the concepts of the chapters through the Jigsaw method and thei...

Evaluation and validation of homology modeling protocols are indispensable for membrane proteins as experimental determination of their three-dimensional structure is an arduous task. The prediction ability of Modeller, MOE, InsightII-Homology and Swiss-PdbViewer (SPV) with different sequence alignments CLUSTALW, BLAST and 3D-JIGSAW have been assessed. The sequence identity of the target and te...

Jigsaw patterns, a graphical architecture description notation, will be presented in this paper. The jigsaw patterns shows components and connectors with their interfaces. Connectors are structures or objects implementing the interfaces. Components are structures interacting via the connectors. Each component and connector can be taken as a new system and decomposed. The semantics of the jigsaw...
