The SP theory and the representation and processing of knowledge

Deblocking Joint Photographic Experts Group Compressed Images via Self-learning Sparse Representation

JPEG is one of the most widely used image compression method, but it causes annoying blocking artifacts at low bit-rates. Sparse representation is an efficient technique which can solve many inverse problems in image processing applications such as denoising and deblocking. In this paper, a post-processing method is proposed for reducing JPEG blocking effects via sparse representation. In this ...

Changing the Role of Teacher according to Complexity Theory: From Representation to Facilitating Emergence

The present study seeks to rethink the role of the teacher in the teaching-learning process according to the complexity theory. First, the role of the teacher is explained in the traditional vision of Comenius and Dewey's critical insight and then the role of the teacher is discussed in the complexity theory. Then, the teacher’s image as an emergence facilitator is suggested instead of their im...

The Role of Architectural Representation on the Formation of the Mental Image of Tourist Destination (Case Study: Traditional Dwellings in the Data Theory Method)

The aim of this study was to explain the role of place representation in shaping the mental image of tourists from traditional residences. Representing the architecture of traditional residences in cyberspace as one of the most important sources of effective information in shaping the image of tourist destinations is of great importance. Today, traditional resorts as one of the most important t...

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...

Spatial Representation and Production and Reproduction of the Mental Image: Lefebvre’s Trialectic Approach

Lefebvre's theory of space production has been very much considered. In particular, it is important to integrate it systematically into the categories of city and space as a comprehensive and comprehensible social theory. Lefebvre's theory of space production has been remarkable in recent years and has responded well to the many questions posed in the early 1970s. Lefebvre in his trialectic in ...
