We propose a novel approach to address the Simultaneous Detection and Segmentation problem introduced in [8]. Using the hierarchical structures first presented in [1] we use an efficient and accurate procedure that exploits the hierarchy feature information using Locality Sensitive Hashing. We build on recent work that utilizes convolutional neural networks to detect bounding boxes in an image ...

In this paper we propose two saliency models for salient object segmentation based on a hierarchical image segmentation, a tree-like structure that represents regions at different scales from the details to the whole image (e.g. gPb-UCM, BPT). The first model is based on a hierarchy of image partitions. The saliency at each level is computed on a region basis, taking into account the contrast b...

The problem of identifying the class of an object from its visual appearance has received significant attention recently. Most of the work to date is premised on photometric measures, often building codebooks made from interest regions. All of it has been tested only on photographs, so far as we know. Our approach differs in two significant ways. First, we do not build a codebook of interest re...

In this paper we present concepts for modelling image processing operators within an object-oriented system like the Smalltalk environment. The operators, which are described in a knowledge-base and receive their functionality from a large, proven, and well-established C library, are integrated into the Smalltalk environment in order to provide this environment with extensive image processing c...

We are interested in eeciently accessing data in an object-oriented database. We have developed a query algebra which fully supports object identity and abstract data types, and have identiied a variety of algebraic query transformations. The equivalence of two queries is complicated by the presence of object identity. In this paper we deene a hierarchy of notions of equivalence for queries, an...

In this paper, we propose a schema version model which allows to restructure complex object hierarchy in object-oriented databases. This model extends a schema version model, called RiBS, which is based on the concept of Rich Base Schema. In the RiBS model, each schema version is in the form of updatable class hierarchy view over one base schema, called the RiBS layer, which has richer schema i...

We report here the results of high-resolution and spectral imaging X-ray observations, with both the ROSAT HRI and PSPC, of the field surrounding the nearby (D = 64Mpc) type 1 Seyfert galaxy IC 4329A and its giant lenticular companion IC 4329. Many point sources are detected, the brightest being associated with IC 4329A itself, having an extremely bright X-ray luminosity of 6 × 1043 erg s−1, an...

An experiment was performed to investigate the ability of human observers to identify configural relations among three dots. Four stimulus categories were defined on the basis of whether or not the dots were arranged collinearly and whether or not the central dot was equally spaced relative to the two flanking dots. Observers were initially trained with feedback to identify these categories at ...

In this research, two techniques of pixel-based and object-based image analysis were investigated and compared for providing land use map in arid basin of Mokhtaran, Birjand. Using Landsat satellite imagery in 2015, the classification of land use was performed with three object-based algorithms of supervised fuzzy-maximum likelihood, maximum likelihood, and K-nearest neighbor. Nine combinations...
