The aim of this research is an improvement of plant seedling recognition by two new
approaches of shape feature generation based on plant silhouettes. Experiments show that …

Dynamic time warping (DTW) has been widely used to align and compare two sequences.
DTW can efficiently deal with local warp or deformation between sequences. However, it …

Shape is considered to be one of the most promising tools to represent and recognise an
object. In this study, an effective and rigorous shape matching algorithm is developed based …

In this paper, we report a study of different preprocessing and classification techniques that
can be applied to shape classification using the signature of the blob, or its FFT, as the main …

One branch of general image processing research deals with 2D object classification where
classes are categorized by different features of the objects such as area, perimeter …

The aim of our work is the development of image analysis tools and methods for the
investigation of drawings and drawn drafts in order to investigate the authorship, to identify …

Transaction based Web services that demand realtime performance guarantees, such as
online auctions, stock trading and real-time database servers generally require a higher …

This paper proposes a drawing tool recognition method based on features calculated from
the shape of stroke endings. The application for this method is to help art historians to …

This thesis proposes a drawing and writing tool recognition algorithm based on features
calculated from the shape of stroke endings. The analysis of strokes is an interdisciplinary …

A near-planar object seen from different viewpoints results in differently deformed images.
Under some assumptions, viewpoint changes can be modeled by affine transformations …
