An evaluation of physically based statistical colour models for image region characterisation

The Characterisation of Colour Printing Devices via Physical, Numerical and LUT Models

The aim of this study was, to derive well-performed four-color printer device characterisation models (DCMs), which were afterwards used to pack up entries of the look up table (LUT) to perform the actual complex colour-image transformations. Based on both non-linear and non-ideal behaviours of primary colorants, two types of printing device characterisation model approaches were proposed in th...

Design, Development and Evaluation of an Orange Sorter Based on Machine Vision and Artificial Neural Network Techniques

ABSTRACT- The high production of orange fruit in Iran calls for quality sorting of this product as a requirement for entering global markets. This study was devoted to the development of an automatic fruit sorter based on size. The hardware consisted of two units. An image acquisition apparatus equipped with a camera, a robotic arm and controller circuits. The second unit consisted of a robotic...

Evaluation and Comparison of Topographic Correction Models Is Applied on the Series Landsat Images Using Spectrometery Data

The effect of topography on the radiance record in satellite image, probably reduce the accuracy of algorithem impliementation on the images . Therefore, to reduce the effect of topography, various correction models based on interaction between light and object needs to be defined. This research introduces lombertin correction model (Cosine model) and non_lombertin correction model (mineart and...

Semantic-Based Image Retrial in the VQ Compressed Domain using Image Annotation Statistical Models

Colour Emotion Models, CIELAB Colour Coordinates, and Iranian Emotional Responses

Ten colour emotional scales, namely, "Warm Cool", "Active-Passive", "Like-Dislike", "Clean-Dirty", "Fresh-Stale", "Modern-Classical", "Heavy-Light", "Hard- Soft", "Tense-Relaxed", and "Masculine-Feminine"are investigated for single-colour stimuli in CIELAB colour space within a psychophysical experiment by forty observers. The relationships between Iranian colour emotional responses and CIELAB ...
