Image segmentation in pyramids

Computer Graphics and Image Processing, 1982
Abstract A method of image segmentation was recently introduced based on defining links between pixels at adjacent levels of a “pyramid” of reduced-resolution versions of the image. This paper studies some of the problems that arise with linked-pyramid segmentation, and proposes a two-stage segmentation process that overcomes these problems.

Image segmentation in thermal images

2016 IEEE International Conference on Industrial Technology (ICIT), 2016
This paper presents a novel method for image segmenting in thermal images. A thermal imaging sensor is a device that forms an image by detecting the infrared radiation from objects in a scene and comparing their temperature differences. In this study, we characterized an object's heat signature (its mean temperature and variance) by segmenting its ...

Image segmentation and image models

Proceedings of the IEEE, 1979
This paper discusses image segmentation techniques from the standpoint of the assumptions that an image should satisfy in order for a particular technique to be applicable to it. These assumptions, which are often not stated explicitly, can be regarded as (perhaps informal) "models" for classes of images.

Image-Measurement Segmentation

Journal of Marketing Research, 1978
Product positioning studies for both new and established products generally involve consumers’ perception of the current product space in terms of the salient product attributes. Perceptions per brand attribute are hypothesized to be a function of direct measurement and brand “image.” The influences of direct measurement and image are separated.

Segmentation in Echocardiographic Images

2002
Echocardiography, ultrasonography of the living heart, has become an important basic tool of diagnosis, treatment evaluation, and research in cardiology. It has achieved a prominent place among the other cardiac imaging modalities for many practical and safety reasons.

Optimal Quadtrees for Image Segments

IEEE Transactions on Pattern Analysis and Machine Intelligence, 1983
Quadtrees are compact hierarchical representations of images. In this paper, we define the efficiency of quadtrees in representing image segments and derive the relationship between the size of the enclosing rectangle of an image segment and its optimal quadtree.

Unsupervised segmentation of color images

Proceedings 1998 International Conference on Image Processing. ICIP98 (Cat. No.98CB36269), 2002
A novel technique for unsupervised learning in feature space is presented. The feature space is considered as composed of two distinct sources, “mode” and “valley”, in the point of view of information theory. An entropy-based thresholding is taken to distinguish the discretized cells in the feature space. The cells labeled as “mode” are then chained to

Image Segmentation by Image Analogies

2014
In this paper we propose a new technique for image segmentation based on contour detection using image analogies principle. A set of artificial patterns are used to locate contours of any query image. Each pattern allow the location of contours corresponding to specific intensity variation.

Image segmentation or image understanding ?

ICASSP '82. IEEE International Conference on Acoustics, Speech, and Signal Processing, 2005
In Image processing, it is often implicitely admitted that an image is known when it has been segmented in various textures, in accordance with the judgement of the human eye. Two counter examples are presented, in biology and in petrology, showing that image analysis may also consist in synthetizing informations disseminated over a large number of ...
