This paper proposes a cluster-to-cluster image color transform algorithm. Suntory Flowers announced the development of world's first blue rose “APPLAUSE”. Since roses lack the blue pigment, it was long believed to be impossible. The key to success lies in the introduction of blue gene from pansy into rose. In the previous paper, PCA matching model was successfully applied to a seasonal color ch...

This paper is devoted to the investigation and development of the algorithm for the log pile photogrammetry measurement on the basis of abuts detection and calculation of their diameters. The algorithm of abuts contours detection and refinement relies on the modified radial symmetry object detection algorithm. The combination of the following methods is implemented at the further stages of the ...

Relevance feedback has been shown as a powerful tool to improve the retrieval performance of content-based image retrieval (CBIR). However, the feedback iteration process is tedious and time-consuming. History log consists of valuable information about previous users’ perception of the content of image and such information can be used to accelerate the feedback iteration process and enhance the...

This paper presents a fast corner fixation algorithm for log-polar cameras. The algorithm uses the log-Hough transform to fixate on the dominant corner in the image by aligning the optical axis with the corner. The algorithm has been implemented in a real-time closed-loop control system, which exhibits stable behaviour as the tracking error minimises towards the image centre. This system demons...

Assessment of the reservoir structure and determination of theinsitu stress direction arenecessary in oil production optimization andfield development. Today, the application of reservoir software and Image logsplay a central role in resolving this problem. Electricand ultrasonic imaging tools record vast amounts of high-resolution data within the borehole wall. This enables the geoscientists t...

This paper investigates, how straight lines are mapped to the non-Euclidean log-polar image plane and how their properties in logpolar coordinates can be used to perform two fundamental measurement operations: the construction of straight lines of given orientation angle and the measurement of distances along these lines. It is shown, how the two operations can be efficiently implemented for di...
