with the explosive growth of the transmission knowledge on the Web, content-based image search has attracted considerable attentions within the transmission and computer vision community. The most common approach is predicated on the bag-of-visual-words model with invariant native options. Since the special context information among native options is important for visual content identification,...

Current approaches to cross-lingual information retrieval (CLIR) rely on standard retrieval models into which query translations by statistical machine translation (SMT) are integrated at varying degree. In this paper, we present an attempt to turn this situation on its head: Instead of the retrieval aspect, we emphasize the translation component in CLIR. We perform search by using an SMT decod...

We present a novel method for 3D-shape matching using Bag-of-Feature techniques (BoF). The method starts by selecting and then describing a set of points from the 3D-object. Such descriptors have the advantage of being invariant to different transformations that a shape can undergo. Based on vector quantization, we cluster those descriptors to form a shape vocabulary. Then, each point selected ...

We have previously proposed a shape-based 3D model retrieval algorithm that compares 3D shape based on local visual features. The method first computes a set of multi-scale local visual features from a set of depth images rendered from multiple view orientations about the 3D model. Thousands of visual features per model are integrated into a feature vector for the model by using so-called bag-o...

Binary code embedding methods can effectively compensate the quantization error of bag-of-words (BoW) model and remarkably improve the image search performance. However, the existing embedding schemes commonly generate binary code by projecting local feature from original feature space into a compact binary space. The spatial relationship between the local feature and its neighbors are ignored....

Image Retrieval is the process of retrieving images from image/multimedia databases. are carried out with various types queries, free-form query a text-query that consists single or multiple keywords and/or concepts descriptions without inclusion wild-card characters punctuations. This work aims to handle image retrieval based on text queries. Simple & complex queries conceptual explored an...

Abstract Aim To compare the outcomes of gallbladder extraction with versus without using retrieval bag in laparoscopic cholecystectomy. Methods The duration study was six months after approval synopsis. After meeting inclusion criteria a total 130 patients were enrolled. Informed consent and demographic detail noted. Patients randomly assorted two groups by lottery method. In group A, extracted...

Abstract Endoscopic submucosal dissection enables en bloc resection of large superficial colorectal neoplasms. However, it is sometimes challenging to retrieve a resected specimen via the anus without sample fragmentation. A novel “bag-type” retrieval device has been developed accomplish complete isolation and non-destructive delivery oversized specimens. This single-center retrospective study ...
