Particle-flow interactive animation for painting image
Abstract In this paper, we present an interactive multimedia artwork, which awakens motionless images to interactive animations. This animation simulates the colour-flow movement from painting […]
Offline handwritten signature recognition using adaptive variance reduction
Abstract Although offline handwritten signature recognition has been continually researched, it still requires an improvement of recognition rate. Most of existing techniques focus on feature […]
Modified differential box-counting method using weighted triangle-box partition
Abstract Differential box-counting (DBC) is one of the commonly used methods to estimate fractal dimension (FD) for gray scale images. It has been successfully applied […]
Improved Triangle Box-Counting Method for Fractal Dimension Estimation
Abstract A fractal dimension (FD) is an effective feature, which characterizes roughness and self-similarity of complex objects. However, the FD in nature scene requires the […]
Adaptive Histogram of Oriented Gradient for Printed Thai Character Recognition
Abstract A similarity of printed Thai characters is a grand challenge of optical character recognition (OCR), especially in case of a variety of font types, […]
Text-background decomposition for thai text localization and recognition in natural scenes
Abstract Thai text localization and recognition in natural scenes is still a grand challenge in current applications. However, the efficiency of recognition rates depends on […]
Font Descriptor Construction for Printed Thai Character Recognition
Abstract The font evolution with various types is a great impact on a recognition performance of optical character recognition (OCR) systems. The more diversity of […]
Printed Thai Character Recognition Using Standard Descriptor
Abstract The various font-types, font-sizes, and font-styles have a great impact on recognition performance of optical character recognition (OCR) systems. This becomes a grand challenge […]
Improved Thai text detection from natural scenes
Abstract Thai text detection from natural scenes is still a challenging task for language translation applications, since there are many unsolved issues. Furthermore, the existing […]
