This paper presents a novel range image segmentation algorithm based on planar surface extraction. The algorithm was applied to common range image databases and was favorably compared against seven other segmentation algorithms using a popular evaluation framework. The experimental results show that, as compared to the other methods, our algorithm presents a good performance in preserving small...

In-field fruit monitoring at different growth stages provides important information for farmers. Recent advances have focused on the detection and location of fruits, although development accurate size estimation systems is still a challenge that requires further attention. This work proposes novel methodology automatic in-field apple which based four main steps: 1) detection; 2) point cloud ge...

The present article proposes a Structure from Motion (SfM) methodology to recover the liver surface from endoscopic video sequences. Features from an imaged liver are extracted and tracked for the complete sequence to generate a correspondences lookup table (C-LUT) between all frames. A keyframe selection code extracts two frames, from which the relative pose of the camera is reconstructed usin...

The random sample consensus (RANSAC) algorithm, along with its many cousins such as MSAC and MLESAC, has become a standard choice for robust estimation in many computer vision problems. Recently, a raft of modifications to the basic RANSAC algorithm have been proposed aimed at improving its efficiency. Many of these optimizations work by reducing the number of hypotheses that need to be evaluat...

Cucumber powdery mildew, which is caused by Podosphaera xanthii, a major disease that has significant economic impact in cucumber greenhouse production. It necessary to develop non-invasive fast detection system for disease. Such will use multispectral imagery acquired at close range with camera attached mobile cart’s mechanic extension. This study evaluated three image registration methods app...

In this paper, a robust technique based on a genetic algorithm is proposed for estimating two-view epipolar-geometry of uncalibrated perspective stereo images from putative correspondences containing a high percentage of outliers. The advantages of this technique are three-fold: (i) replacing random search with evolutionary search applying new strategies of encoding and guided sampling; (ii) ro...

In recent years, the focus in biological science has shifted to understanding complex systems at the cellular and molecular levels, a task greatly facilitated by fluorescence microscopy. Segmentation, a fundamental yet difficult problem, is often the first processing step following acquisition. We have previously demonstrated that a stochastic active contour based algorithm together with the co...
