Scale- and orientation-invariant scene similarity metrics for image queries

In this paper we extend our previous work on shape-based queries to support queries on configurations of image objects. Here we consider spatial reasoning, especially directional and metric object relationships. Existing models for spatial reasoning tend to rely on pre-identified cardinal directions and minimal scale variations, assumption that cannot be considered as given in our image applica...

Spatial-Scene Similarity Queries

Assessing spatial scenes for similarity is difficult from a cognitive and computational perspective. Solutions to spatial-scene similarity assessments are sensible only if corresponding elements in the compared scenes are identified correctly. This matching process becomes increasingly complex and error-prone for large spatial scenes as it is questionable how to choose one set of associations o...

Region-Based Image Retrieval with Scale and Orientation Invariant Features

In this paper, we address the problem of image retrieval when the query is in the form of scaled and rotated regions of images in the database. The solution lies in identifying points that are invariant to scaling and rotation and determining a robust distance measure that returns images that contain the query regions. We use the Harris-Laplacian detector to detect the interest points which are...

Invariant error metrics for image reconstruction.

Expressions are derived for the normalized root-mean-square error of an image relative to a reference image. Different versions of the error metric are invariant to different combinations of effects, including the image's (a) being multiplied by a real or complex-valued constant, (b) having a constant added to its phase, (c) being translated, or (d) being complex conjugated and rotated 180 degr...

Pictorial queries by image similarity

A method for specifying pictorial queries to an image database is introduced. A pictorial query specification consists of a query image, and a similarity level that specifies the required extent of similarity between the query image and database images that are to be retrieved. The query image is constructed by positioning objects so that the desired locational and spatial constraints hold. Two...
