Jump-Miss Binary Erosion Algorithm
Found in: Graphics, Patterns and Images, SIBGRAPI Conference on
By Anderson Fraiha Machado, Ronaldo Fumio Hashimoto
Issue Date:October 2009
pp. 149-155
This work presents a new and fast algorithm for binary morphological erosions with arbitrary shaped structuring elements inspired by preprocessing techniques that are quite similar to those presented in many fast string matching algorithms (jumps and miss-...
 
A New Training Algorithm for Pattern Recognition Technique Based on Straight Line Segments
Found in: Graphics, Patterns and Images, SIBGRAPI Conference on
By João Henrique Burckas Ribeiro, Ronaldo Fumio Hashimoto
Issue Date:October 2008
pp. 19-26
Recently, a new Pattern Recognition technique based on straight line??segments (SLSs) was presented. The key issue in this new technique??is to find a function based on distances between points and two sets??of SLSs that minimizes a certain error or risk c...
 
A New Machine Learning Technique Based on Straight Line Segments
Found in: Machine Learning and Applications, Fourth International Conference on
By Joao Henrique Burckas Ribeiro, Ronaldo Fumio Hashimoto
Issue Date:December 2006
pp. 10-16
This paper presents a new supervised machine learning technique based on distances between points and straight lines segments. Basically, given a training data set, this technique estimates a function where its value is calculated using the distance betwee...
 
Extraction of Numerical Residues in Families of Levelings
Found in: 2013 XXVI SIBGRAPI - Conference on Graphics, Patterns and Images (SIBGRAPI)
By Wonder Alexandre Luz Alves,Alexandre Morimitsu,Joel Sanchez Castro,Ronaldo Fumio Hashimoto
Issue Date:August 2013
pp. 349-356
This work introduces a residual operator called ultimate attribute leveling. We also present an efficient algorithm for ultimate attribute leveling computation by using a structure called tree of shapes. Our algorithm for computating ultimate attribute lev...
 
Text Regions Extracted from Scene Images by Ultimate Attribute Opening and Decision Tree Classification
Found in: Graphics, Patterns and Images, SIBGRAPI Conference on
By Wonder Alexandre Luz Alves, Ronaldo Fumio Hashimoto
Issue Date:September 2010
pp. 360-367
In this work we propose a method for localizing text regions within scene images consisting of two major stages. In the first stage, a set of potential text regions is extracted from the input image using residual operators (such as ultimate attribute open...
 
A Note on Park and Chin's Algorithm
Found in: IEEE Transactions on Pattern Analysis and Machine Intelligence
By Ronaldo Fumio Hashimoto, Junior Barrera
Issue Date:January 2002
pp. 139-144
<p>A finite subset of ZZ^2 is called a structuring element. A decomposition of a structuring element A is a sequence of subsets of the elementary square (i.e., the 3 x 3 square centered at the origin) such that the Minkowski addition of them is equal...
 
A Simple Algorithm for Decomposing Convex Structuring Elements
Found in: Graphics, Patterns and Images, SIBGRAPI Conference on
By Ronaldo Fumio Hashimoto, Junior Barrera
Issue Date:October 1999
pp. 275
A finite subset of Z2 is called a structuring element. This paper presents a new and simple algorithm for decomposing a convex structuring element as sequence of Minkowski additions of a minimum number of subsets of the elementary square (i.e., the 3 by 3 ...
 
Growing Seed Genes from Time Series Data and Thresholded Boolean Networks with Perturbation
Found in: IEEE/ACM Transactions on Computational Biology and Bioinformatics (TCBB)
By Carlos H. A. Higa, Ronaldo Fumio Hashimoto, Tales P. Andrade
Issue Date:January 2013
pp. 37-49
Models of gene regulatory networks (GRN) have been proposed along with algorithms for inferring their structure. By structure, we mean the relationships among the genes of the biological system under study. Despite the large number of genes found in the ge...
