Image Measurement with Statistical Analysis

Fragmentation measurement using image processing

In this research, first of all, the existing problems in fragmentation measurement are reviewed for the sake of its fast and reliable evaluation. Then, the available methods used for evaluation of blast results are mentioned. The produced errors especially in recognizing the rock fragments in computer-aided methods, and also, the importance of determination of their sizes in the image analysis ...

Statistical Analysis of Text in Educational Measurement

This paper describes tools developed at Educational Testing Service which use statistical modeling of textual corpora to provide automated assessments of student responses. Details are given for three of these systems: Critique Writing Analysis Tools for providing feedback to students, e-rater for assigning a holistic score to student essays, and c-rater, which scores responses to content-based...

Full Reference Printed Image Quality: Measurement Framework and Statistical Evaluation

Full reference image quality algorithms are standard tools in digital image processing but have not been utilized for printed images due to a “correspondence gap” between the digital domain (a reference) and physical domain (printed sample). In this work, the authors propose a framework for applying full reference image quality algorithms to printed images. The framework consists of accurate sc...

Image analysis and statistical modelling for measurement and quality assessment of ornamental horticulture crops in glasshouses

Image analysis for ornamental crops is discussed with examples from the bedding plant industry. Feed-forward artificial neural networks are used to segment top and side view images of three contrasting species of bedding plants. The segmented images provide objective measurements of leaf and flower cover, colour, uniformity and leaf canopy height. On each imaging occasion, each pack was scored ...
