The main issue in the digital content marketplace is copyright protection of digital content. Sometimes the digital information may copy or alter during transmission. Thus, there is a need to develop an authentication method, which is very effective to protect the digital data. There are different watermarking techniques, which use different transforms. In this paper, a Discrete Wavelet Transform...
A study of core problem in the packaged granary grain intelligent detection based on image recognition was conducted, and an intelligent detection method combining Fisher criterion with Adaptive Genetic Algorithm was used to solve it. We took the actual scene video as the analysis object, and the constructed Fisher criterion as the fitness function of Genetic Algorithm, while we presented a local...
This paper presents the use of genetic algorithm in old document image enhancement and restoration. The term of `old document' is document coming from hundreds years ago. The purpose of the study is to preserve the information contained in old documents into a digital form, because the process to rescue the old images using physical approach is too slow. The main contribution of this study is in the...
Several methods have been developed to generate terrains under constraints to control terrain features, but most of them use strict restrictions. However, there are situations were more flexible restrictions are sufficient, such as ensuring that terrains have enough accessible area, which is an important trait for video games. Many terrains, generated with Genetic Terrain Program technique, based...
In this paper, an image matching algorithm based on morphology description matrix and genetic algorithm is proposed to improve matching efficiency. For the non-ergodic search characteristic of genetic algorithm is utilized, the global optimization is improved rapidly. Moreover, a shape matching algorithm based on the similarity of morphology description matrix is used in this paper. The calculation...
Road recognition from SAR image is a very important problem. In this paper, a new method is proposed which can detect multiple roads in an image. Firstly binary edge image is gained by Canny operator and edge refining. Secondly, edge curves are encoded by reversible chained list, and fitness function is constructed based on SAR image road models, and optimal road boundary curves are linked by improved...
