Tessella-oriented segmentation and guidelines estimation of ancient mosaic images

Tessella-oriented segmentation and guidelines estimation of ancient mosaic images

Automatic segmentation and analysis of ancient mosaic images can help archeologists and experts build digital collections and automatically compare mosaics by means of image database indexing and content-based retrieval tools. However, ancient mosaics are characterized by low contrast colors, irregular tessella shape, orientation and positioning, making automatic segmentation difficult. In this...

Performance Analysis of Segmentation of Hyperspectral Images Based on Color Image Segmentation

Image segmentation is a fundamental approach in the field of image processing and based on user’s application .This paper propose an original and simple segmentation strategy based on the EM approach that resolves many informatics problems about hyperspectral images which are observed by airborne sensors. In a first step, to simplify the input color textured image into a color image without tex...

Object Oriented Motion and Deformation Estimation Using Composite Image Segmentation

In this paper a novel object oriented motion estimation algorithm is presented. The algorithm provides the means for highly efficient moving image encoding by fully exploiting the temporal r e dundancy among the objects of successive frames. Two-dimensional segmentation is performed on a composite image synthesised from two consecutive frames. The object correspondence problem is removed implic...

Motion Estimation and Figure-Ground Segmentation Using Log-Polar Images

A motion estimation algorithm for log-polar images, based on a previous general framework [2], is presented. The advantages and disadvantages brought by the use of this kind of foveal imaging are discussed. Within this context, a simple, but quite effective approach for figure-ground segmentation is also proposed. Performance results concerning motion estimation and target segmentation are repo...
