This paper presents an image blending approach which combines optimal seam finding and transition smoothing for merging a set of aligned source images into a composite panoramic image seamlessly. In this approach, graph cut optimization is used for finding optimal seams in overlapping areas of the source images to create a composite image. If the seams in the composite image are still visible, ...

In this paper, geostatistical analysis of digital image processing data efficiently contributed to the preliminary site investigation and geotechnical mapping Wadi Fayidah, Saudi Arabia. 3D modeling, clustering, chart pattern changes were used analyze spectral electromagnetic energy reflected values in red, green, blue (RGB) ranges on false color composite Landsat-7 images. Therefore, from upst...

Rodent monitoring in biomedical laboratories is a time consuming and tedious task. Several automatic solutions that rely on different types of sensors have been proposed. Computer vision provides a significantly more universal and less intrusive solution. In this article we propose a new method to detect and classify three behaviors in rodents: Exploring, Rearing, and Static. The method uses Mo...

We describe a novel approach to produce color composite images from hyperspectral data using weighted spectra averages. The weighted average is based on a sequence of numbers (weights) selected using pixel value information and interband distance. Separate sequences of weights are generated for each of the three color bands forming the color composite image. Tuning of the weighting parameters a...

INTRODUCTION: Bright-field microscopy suffers from a relatively small depth-of-field. Typically, the specimen’s profile covers a range larger than the depth-of-field, and parts of the specimen that lie outside the object plane appear blurred. The specimen can be ‘scanned’ by moving the object along the optical axis, and different images will contain different areas that are sharp. The purpose o...

objectives: this study aimed to assess the effects of two energy drinks on color change (∆e) of two methacrylate-based and a silorane-based composite resin after one week and one month. materials and methods: thirty cubic samples were fabricated from filtek p90, filtek z250 and filtek z350xt composite resins. all the specimens were stored in distilled water at 37°c for 24 hours. baseline color ...

The eastern Lut block of Iran has a high potential for porphyry copper mineralization due to the subduction tectonic regime. It is located in an inaccessible region and harsh arid conditions traditional mineral exploration campaigns. objective this study use Advanced Spaceborne Thermal Emission Reflection Radiometer (ASTER) remote sensing data Simorgh Area, Iran. Hydrothermal alteration zones s...

In this paper, we present a blind image restoration algorithm to reconstruct a high resolution (HR) color image from multiple, low resolution (LR), degraded and noisy images captured by thin (< 1mm) TOMBO imaging systems. The proposed algorithm is an extension of our grayscale algorithm reported in [1] to the case of color images. In this color extension, each Point Spread Function (PSF) of eac...

With increased digital images in image repositories efficient indexing and searching becomes essential for large image archives. Content based image retrieval system (CBIR) retrieve relevant images using low-level features like color, texture and shape for image representation. In this approach, a scheme of novel color image retrieval based on visual interest point is presented. The existing sy...
