Tracking trajectory of three-dimensional trees is a difficult problem in computer animation and virtual reality. It requires not only high sense of reality for the morphology of trees and tree moving, but also adequate real-time. In this paper, we present a simulation method based on video data driven. Firstly, split out the main branches and leaves of trees from video images by using hybrid method...
Serial number is an important component to paper money. It is an important identifier to every piece of paper money. This paper presents an effective method on segmentation and recognition of RMB serial number. This methodology can be classified as three stages: preprocessing stage, Serial number segmentation stage and serial number recognition stage. The original serial number image is greylized...
In this paper, an automatic cloud-contaminated area detection approach is studied using multi-temporal middle-spatial satellite remote sensing images. A cloud detection method using multi-temporal images based on change detection method in remote sensing image interpretation and timing information are applied. This approach is composed of three models. Firstly, image preprocessing is applied to image...
This paper proposes a semi-supervised spectral clustering algorithm combined with Bayes decision, for Low stability and accuracy of spectral clustering algorithm. This method is clustered according to color, texture and spatial characteristics of the image. It first adjusts the similarity matrix by distance learning methods based on Bayes decision to improve clustering distribution of feature vectors,...
Forensic image database plays an important role in public security area. In order to narrow down the 'semantic gap' between the abundant semantic meanings of the query and the low-level image features, and to improve the precision of the content-based image retrieval (CBIR) for forensic images, this paper proposes a method which combines region semantic template with the ontology describing the relationship...
The traditional artificial cigarette review methods are difficult to match the high-speed automatic cigarette sorting system. In this paper, a new cigarette recognition method using the uniqueness of cigarette bar codes was proposed. Firstly, a binary image filtering algorithm based on square adaptive structure element of mathematical morphology (SASEMM) was used to get several potential sub-regions,...
