A Heuristic Based on the Intrinsic Dimensionality for Reducing the Number of Cyclic DTW Comparisons in Shape Classification and Retrieval Using AESA
Palazón González, Vicente; Marzal Varó, Andrés Springer Berlin Heidelberg (2012)Cyclic Dynamic Time Warping (CDTW) is a good dissimilarity of shape descriptors of high dimensionality based on contours, but it is computationally expensive. For this reason, to perform recognition tasks, a method to ... -
EM Training of Hidden Markov Models for Shape Recognition Using Cyclic Strings
Palazón González, Vicente; Marzal Varó, Andrés; Vilar Torres, Juan Miguel Springer Berlin Heidelberg (2013)Shape descriptions and the corresponding matching techniques must be robust to noise and invariant to transformations for their use in recognition tasks. Most transformations are relatively easy to handle when contours are ... -
On hidden Markov models and cyclic strings for shape recognition
Palazón González, Vicente; Marzal Varó, Andrés; Vilar Torres, Juan Miguel Elsevier (2014)Shape descriptions and the corresponding matching techniques must be robust to noise and invariant to transformations for their use in recognition tasks. Most transformations are relatively easy to handle when contours ... -
On the Dynamic Time Warping of Cyclic Sequences for Shape Retrieval
Palazón González, Vicente; Marzal Varó, Andrés Elsevier (2012)In the last years, in shape retrieval, methods based on Dynamic Time Warping and sequences where each point of the contour is represented by elements of several dimensions have had a significant presence. In this approach ... -
Speeding up the cyclic edit distance using LAESA with early abandon
Palazón González, Vicente; Marzal Varó, Andrés Elsevier (2015)The cyclic edit distance between two strings is the minimum edit distance between one of this strings and every possible cyclic shift of the other. This can be useful, for example, in image analysis where strings describe ...
