Content Centric Networking (CCN) is a new network architecture around content dissemination and retrieval. Its request–response and in-network caching mechanisms can significantly improve the network performance in reducing the transmission delay. However, the in-network caching may prevent the network coding technique from being applied into CCN because cached coded blocks may not be linearly ...

Document image matching is the key technique for document image registration and retrieval. In this paper, a new matching method based on document component block list (CBL) is proposed. A document image is ®rstly parsed into a number of component blocks that are de®ned as non-adherent rectangular areas of substantial document contents. Then these blocks are organized as a list, on which severa...

Thoracic posterior joints are putative pain generators; yet there is a paucity of information to assist the clinician in the diagnosis and treatment of dorsal spine pain. A safe and effective bent needle injection/arthrography technique is described which can assist in the diagnosis of some patients with thoracic zygapophyseal joint dysfunction.

This contribution investigates the content-based feature extraction methods used in visual information retrieval, focusing on concepts that are employed for the semantic representation of media content. The background part describes the building blocks of feature extraction functions. Since numerous methods have been proposed we concentrate on the metaconcepts. The building blocks lead to a dis...

much attention has recently been paid to natural language processing in information storage and retrieval. this paper describes how the application of natural language processing ( nlp ) techniques can enhance cross-language information retrieval ( clir ). using a semi-experimental technique, we took farsi queries to retrieve relevant documents in english. for translating persian queries, we us...

in this paper we propose novel algorithms for retrieving dental images from databases by their contents. based on special information of dental images, for better content based dental image retrieval and representation, the image attributes are used. we propose disr (dental image segmentation and retrieval), a content-based image retrieval method which is robust to translation and scaling of th...

As the wide application of imaging technology, number big image data which may containing private information is growing fast. Due to insufficient computing power and storage space for local server device, many people hand over these images cloud servers management. But actually, it unsafe store cloud, so encryption becomes a necessary step before uploading reduce risk privacy leakage. However,...

The compressed domain is appealing for the image retrieval because of the direct efficient feature extraction; moreover, currently almost all the images are available in a compressed format using the Discrete Cosine Transformation (DCT). In this paper, the quantized histogram statistical texture features are extracted from the DCT blocks using the significant energy of the DC and the first thre...
