چکیده

In this paper, an e cient image content representation is proposed, which is appropriate for content-based indexing and retrieval. In particular, the image content is represented by a hierarchical graph, constructed in a tree or pyramid structure framework. The basic concept is to represent the spatial relations of the objects in the image with an image-graph and then, the object details with an object-graph. Further decomposition of the objects regions is permitted in a hierarchical framework.

Scalable Image Annotation by Summarizing Training Samples into Labeled Prototypes

By increasing the number of images, it is essential to provide fast search methods and intelligent filtering of images. To handle images in large datasets, some relevant tags are assigned to each image to for describing its content. Automatic Image Annotation (AIA) aims to automatically assign a group of keywords to an image based on visual content of the image. AIA frameworks have two main sta...

Efficient Content-Based Retrieval of Humans from Video Databases

An efficient algorithm for humans’ retrieval from large video databases is presented in this paper. Such an extraction is very useful for a variety of applications, including video surveillance for security purposes and systems of speaker identification. A human face and body detector is first proposed, based on a simple probabilistic model, to approximately estimate human face and body regions...

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...

Non-Linear Image Representation Based on IDP with NN

In this paper is offered a method for non-linear still image representation based on pyramidal decomposition with a neural network. This approach is developed by analogy with the hypothesis for the way humans do image recognition using consecutive approximations with increasing similarity. A hierarchical decomposition, named Inverse Difference Pyramid (IDP), is used for the image representation...
