Many orchids could be successfully cultivated outside of their natural habitat, and they have grown in popularity immensely. They represent one of the most admired plant families grown and are now the most valuable floriculture crop produced in Thailand and many other countries. Unfortunately, some rare orchids are among the most difficult plants for discovery and for finding proper places for species...
This paper proposed an improvement of genetic algorithm for optimization problem. In this study, the Gaussian function is applied in crossover and mutation operators instead of traditional crossover and mutation. The algorithm is tested on five benchmark problems and compared with the self-adaptive DE algorithm, traditional differential evolution (DE) algorithm, the JDE self-adaptive algorithm and...
This paper proposes a hybrid bat algorithm with natural-inspired algorithms for continuous optimization problem. In this study, the proposed algorithm combines the reproduction step from weed algorithm and genetic algorithm. The reproduction step is applied to clone each bat population by fitness values and the genetic algorithm is applied in order to expand the population. The algorithm is evaluated...
This paper proposes a new character recognition system for archaic Lanna handwritten characters. The proposed system consists of two main processes: the segmentation process and the recognition process. The segmentation process decomposes the touching or overlapping characters, commonly found in Lanna manuscripts, into isolated characters. In the recognition process, the proposed system uses the self-organizing...
Lanna script is an archaic script not commonly used in today's world. People trying to read these archaic Lanna manuscripts have to find some form of translation help to understand what they said. Unfortunately, few people nowadays know how to read or write this language. Therefore, character recognition system must be put to use in order to translate the Lanna script to the commonly used script....
Character segmentation is an important preprocessing step for character recognition. Incorrectly segmented characters are not likely to be correctly recognized. Touching characters is one of the most difficult segmentation cases which arise when handwritten characters are being segmented. Therefore, this paper emphasizes the interest to the segmentation of touching and overlapping characters. In the...
