This paper presents a novel approach for both fast and accurately retrieving similar shapes. A hierarchical string cuts (HSC) method is proposed to partition shape into multiple level curve segments of different lengths from point moving around the contour describe gradually completely global information finest details. At each level, are cut by strings extract features that characterize geometric distribution properties in particular The translation, rotation, scale mirror invariant HSC...
Most researches involved so far in kiwifruit harvesting robot suggest the scenario of daytime for taking advantage sunlight. A operating at nighttime can overcome problem low work efficiency and would help to minimize fruit damage. In addition, artificial lights be used ensure constant illumination instead variable natural sunlight image capturing. This paper aims study recognition using lighting based on machine vision. Firstly, an RGB camera was placed underneath canopy that clusters...
As an inversion-based imaging algorithm, least-squares reverse time migration (LSRTM) refines seismic images toward true-reflectivity earth models. It overcomes the shortcomings of conventional algorithms via iterative inversion to gradually correct errors. LSRTM also suppresses side lobes image wavelets generate with high spatial resolution. Recovered weak events and steep dips are enhanced during iterations balanced illumination. The true-amplitude behavior will greatly benefit...
Effectively describing and recognizing leaf shapes under arbitrary deformations, particularly from a large database, remains an unsolved problem. In this research, we attempted new strategy of shape by walking along bunch chords that pass through the to measure regions trespassed. A novel chord walks (CBW) descriptor is developed effectively integrates image function over walked reflect contour features inner properties shape. For each point, groups multiple pairs build hierarchical...

A novel shape description method is proposed for mobile retrieval of leaf images to aid in plant recognition. In this method, traveling the contour, convexity and concavity properties arches various levels are measured, respectively, generate a multiscale descriptor. Its performance has been tested on two datasets experimental results indicated higher recognition accuracies than state-of-the-art approaches with speed improvement more 170 times. The successfully applied develop prototype...
In this paper, we present a novel mathematical tool, Structure Integral Transform (SIT), for invariant shape description and recognition. Different from the Radon (RT), which integrates image function over 1D line in plane, proposed SIT builds upon two orthogonal integrals 2D K -cross dissecting structure spanning across all rotation angles by regions are bisected each integral. The brings following advantages RT: 1) it has extra of describing interior structural relationship within provides...
Leaf identification is a significant and challenging task for computer vision community due to the large intra-class variations small inter-class differences of leaf image patterns. In this paper, novel shape descriptor, called Integral Contour Angle (ICA), proposed accurate classification retrieval images. For contour point, two bunches vectors emanate from it ends at its left neighbor points right ones respectively. Their average form an angle (termed ICA) having inherent invariance...
Intertidal habitats are among the harshest environments on planet, and have emerged as a model system for exploring ecological impacts of global climate change. Deploying reliable instrumentation to measure environmental conditions such temperature is challenging in this environment. The application wireless sensor networks (WSNs) shows considerable promise means optimizing continuous data collection, but poor link quality unstable connections between nodes, caused by harsh physical...
