Similarity between polygonal shapes
… we review existing algorithms for measuring shape similarity between polygons. We present a new approach to measure similarity based on the notion of annular profile. We also present the implementation of three shape measuring algorithms: signature function, turning function, and annular …

Protein Shape Description and its Application to Shape Comparison
… specifically, by using the structure density-map shape similarity instead of sequence or model similarity. Therefore, this project introduces a mathematical framework for computing three different measures of macromolecular three-dimensional shape similarity and demonstrates how these descriptors …

Shape Analysis in Bioinformatics
… that pesticide toxicity is related to the shape similarity between the pesticide molecule itself and the natural ligand of the protein to which a pesticide will bind (and ultimately cause toxicity). A ligand of aprotein is simply a small molecule that will bind to that protein. It seems …

Digital Library Services for Three-Dimensional Models
… (3) How can we represent the user's view on similarity between two objects? (4) What search types can be used to enhance the usability of the digital library and how can we implement these searches, what are the trade-offs?</p> <p>In this research, we have developed a digital library …

A shape-based approach for image retrieval in healthcare information infrastructure
… some models and techniques that would help build shape-based image retrieval with an improved accuracy. As an initial step, a modular prototype system, called BrainSearch was implemented and used to demonstrate the utility of our algorithms and techniques on brain Magnetic Resonance Imaging (MR1) …

A novel automated approach of multi-modality retinal image registration and fusion
… pixels using adaptive exploratory algorithm. Shape similarity criteria are employed to match the control points. The second contribution is the heuristic optimization algorithm that maximizes Mutual-Pixel-Count (MPC) objective function. The initially selected control points are adjusted during …

Automated Building Information Extraction and Evaluation from High-resolution Remotely Sensed Data
… The proposed system consists of matched rate, shape similarity, and positional accuracy. Experimentation with four methods demonstrates that the proposed multi-criteria system is more comprehensive and effective, in comparison with traditional accuracy assessment metrics. Building height is …

Infants' reasoning about animals
… expect animals of the same kind (as indicated by shape similarity) to share food preferences – a kind relevant property, but not the same toy preferences – a kind irrelevant property. These contrasting results suggest that infants did not simply expect similar objects to share similar non-obvious …

ML-CHIEFS: machine learning-based corneal-specular highlight imaging for enhancing facial recognition security
… accuracy from 86.05% with the reflection shape similarity alone to 99.00% with the ResNet-50-V2 architecture. MobiDeep is a real-time, cloudless, lightweight mobile application for human visual DeepFake detection using ML technologies, which achieved high accuracy (98.7%) and rapid …

Non-cohesive bank migration in meandering rivers and bank accretion in weakly braided rivers
… bank? (b) What is the expected cross-sectional shape of such a channel? Due to the difficulties in establishing freely meandering channels in non-cohesive materials in a laboratory setting, even empirically-based answers to these questions are lacking. The analysis herein attempts to shed light …
