The goal of this study is to present a concept to identify overlapping rubber tree (Hevea brasiliensisscientific name) leaf boundaries. Basically rubber tree leaves show similarity to each other and they may contain similar information such as color, texture or shape of leaves. In fact rubber tree leaves are naturally in class of palmate leaves, it means that numbers of leaves are joining at th...

We present a way to make environmental recordings controllable again by the use of continuous annotations of the high-level semantic parameter one wishes to control, e.g. wind strength or crowd excitation level. A partial annotation can be propagated to cover the entire recording via cross-modal analysis between gesture and sound by canonical time warping (CTW). The annotations serve as a descr...

In this paper we present a hardware accelerated alternative for the accumulation buffer. Multiple frames are accumulated in a hierarchical way, using texturing and programmable graphics hardware. The new algorithm has significant advantages over existing approaches and can be implemented on almost any recent consumer level graphics hardware architecture.

In very few mobile robotic applications stereovision based mapping and navigation is used because dealing with stereo images is very hard and time consuming. Despite all the problems, stereovision still becomes one of the most important resources of knowing the world for a mobile robot because imaging provides much more information of the world than most other sensors. Real robotic applications...

In modern visual information retrieval systems, visual content is directly addressed by features such as color, texture, shape and spatial relationship. While a large work is being done around the perceptual soundness of models and around the automatic extraction of features, only a limited attention is placed on the combination of useful representations and similarity models with efficient ind...

We show how to continuously map a texture onto a 3D triangle mesh when some of the mesh vertices are constrained to have given (u,v) coordinates. This problem arises frequently in interactive texture mapping applications and, to the best of our knowledge, a complete and efficient solution is not available. Our techniques always guarantee a solution by introducing extra (Steiner) vertices in the...

For texture images, an interesting method that reorders DCT coefficients to produce image sub-bands in a multiresolution decomposition-like form and computes the absolute mean value and standard deviation of each subband to construct a feature vector has been proposed in [4]. This method is called MRDCT for multi-resolution reordered DCT. One limitation of MRDCT is that all the DCT sub-bands we...

We apply rough set methods and boolean reasoning for knowledge discovery from decision tables. It is not always possible to extract general laws from experimental data by computing rst all reducts 12] of a decision table and next decision rules on the basis of these reducts. We investigate a problem how information about the reduct set changes in a random sampling process of a given decision ta...

A new texture analysis approach is applied to the problem of classiication of pathological states from electron microscopy images of mouse liver cell nuclei. For each pixel in the image, a region of consistent connected neighbouring pixels is extracted, forming a local texel of pixels belonging to the same gray level population. The geometric properties of each texel is described by invariant m...
