Global Interior Robot Localisation by a Colour Content Image Retrieval System
We propose a new global localisation approach to determine a coarse position of a mobile robot in structured indoor space using colour-based image retrieval techniques. We use an original method of colour quantisation based on the baker’s transformation to extract a two-dimensional colour pallet combining as well space and vicinity-related information as colourimetric aspect of the original ima...
متن کاملMetrics for Image Retrieval by Colour Content
We consider a functional-analytic setting for querying large image databases by colour content, in which the colour distributions (histograms), describing the colour content of an image, are probability measures on the colour space C. The Kantorovich distance turns out to be among the most relevant metrics on the space of colour distributions. We study the colour histogram space equipped with a...
متن کاملA Novel Method for Content Base Image Retrieval Using Combination of Local and Global Features
Content-based image retrieval (CBIR) has been an active research topic in the last decade. In this paper we proposed an image retrieval method using global and local features. Firstly, for local features extraction, SURF algorithm produces a set of interest points for each image and a set of 64-dimensional descriptors for each interest points and then to use Bag of Visual Words model, a cluster...

متن کاملColour and Positional Quantisation for Content-Based Image Retrieval
Colour-based retrieval is one of the major content-based retrieval techniques. The main idea used for colour based retrieval techniques is to store the image in terms of a colour map which has a nite set of colour bins. An eecient retrieval scheme should preserve all the distinct colours of an image with a small number of colour bins. Uniform Quantisation is one of the major quantisation techni...
