Leaf Vein Extraction Based on Gray-scale Morphology

Leaf features play an important role in plant species identification and plant taxonomy. The type of the leaf vein is an important morphological feature of the leaf in botany. Leaf vein should be extracted from the leaf in the image before discriminating its type. In this paper a new method of leaf vein extraction has been proposed based on gray-scale morphology. Firstly, the color image of the...

Invariant Features for Gray Scale Images

Invariant features are image characteristics which remain unchanged under the action of a transformation group. We consider in this paper image rotations and translations and present algorithms for constructing invariant features. After brieey sketching the theoretical background we develop algorithms for recognizing several objects in a single scene without the necessity to segment the image b...

Recognition with Second-Order Topographic Surface Features

We previously[3] defined eight second-order volumetric primitives and then showed[4] that they can be extracted from range data. This paper shows that by using them model matching is more efficient, because the shape vocabulary reduces the combinatorial generation of hypotheses. With the model-to-data correspondences, accurate three dimensional model location is possible.

I-50: Gray Scale and Doppler Features of Retained Products of Conception and Placenta Accrete

Background Postpartum bleeding is a component of the normal physiologic process that occurs after delivery or miscarriage. Normally, bleeding decreases over the first postpartum week. When bleeding is excessive and uterine atony has been excluded as a cause, the next most common cause of postpartum bleeding is retained products of conception (RPOC). The placenta usually constitutes the majority...

Stroke Extraction from Gray-Scale Character Image

In this paper, a topographic feature classification method based on 4directional scanning, and a stroke extraction method from skeletal pixels are proposed. Combination of the proposed methods is relatively fast and the resulting strokes are more acceptable.
