HCL: A Language for Low-Level Image Analysis
نویسنده
چکیده
Pyramids have received a great deal of interest as a data structure for use in hierarchical computer vision. This paper describes a language for the description of pyramid algorithms, supporting conceptually parallel pattern-matching and arithmetic operations. The language is defined by adding constructs from a notation for pyramid algorithms called Hierarchical Cellular Logic to the general-purpose programming language C. Initially developed to support vision research on PCLIP II, a cellular processor with a pyramidal interconnection topology, the language is also implementable on a wide range of parallel architectures.

Image Classification via Sparse Representation and Subspace Alignment
Image representation is a crucial problem in image processing where there exist many low-level representations of image, i.e., SIFT, HOG and so on. But there is a missing link across low-level and high-level semantic representations. In fact, traditional machine learning approaches, e.g., non-negative matrix factorization, sparse representation and principle component analysis are employed to d...
متن کاملExecution of A Requirement Model in Software Development
Latest research results have shown that requirements errors have a prolonged impact on software development and that they are more expensive to fix during later stages than early stages in software development. Use case diagrams in UML are used to give requirements for a software system, but all descriptions for each use case are written in informal language. In this paper, we propose a new lan...
متن کاملTags Re-ranking Using Multi-level Features in Automatic Image Annotation
Automatic image annotation is a process in which computer systems automatically assign the textual tags related with visual content to a query image. In most cases, inappropriate tags generated by the users as well as the images without any tags among the challenges available in this field have a negative effect on the query's result. In this paper, a new method is presented for automatic image...
متن کاملThe Impact of Practicing van Dijk’s Model of Critical Discourse Analysis on the Improvement of Iranian EFL Undergraduates’ Critical Thinking across Different Proficiency Levels
Despite the saliency of raising critical thinking not only in ELT but also in other aspects of life, there is still lack of studies in this regard that need to be filled. Previous studies dealt with Faiclough’s model not that of van Dijk, and besides, they weren’t concerned about CDA effects on different proficiency levels. The present study, however, examined the impact of critical discourse a...
متن کاملA Robust Image Denoising Technique in the Contourlet Transform Domain
The contourlet transform has the benefit of efficiently capturing the oriented geometrical structures of images. In this paper, by incorporating the ideas of Stein’s Unbiased Risk Estimator (SURE) approach in Nonsubsampled Contourlet Transform (NSCT) domain, a new image denoising technique is devised. We utilize the characteristics of NSCT coefficients in high and low subbands and apply SURE sh...
