Undoubtedly, we are living in era of digital information and technology. In this revolutionized world of digital information, we are exposed to a remarkable array of visual imagery. With sophisticated image editing tools and software‟s, it is very easy to manipulate and temper the digital images, thereby questioning the trustworthiness of it. This paper presents a method based on a statistical ...

Coarse aggregate shape (flat and elongated) is an important issue in the highway industry. Elongated aggregates tend to break down during the asphalt emplacement process. Flat aggregates tend to lay flat, imparting anisotropic properties to the finished product. The new Superpave guidelines call for no more than 10% of coarse aggregates to have aspect ratios greater than 5:1, and there is a pos...

A system for monitoring movement of the free-living second stage juveniles of root-knot nematodes (Meloidogyne spp.) using digital image analysis is described. The method is based on the analysis of video sequences of movement of individual random nematodes encumbered with or without Pasteuria penetrans endospores. Software packages were used to grab video images, to process images and to monit...

In this work, the possibilities for segmentation of cells from their background and each other in digital image were tested, combined and improoved. Lot of images with young, adult and mixture cells were able to prove the quality of described algorithms. Proper segmentation is one of the main task of image analysis and steps order differ from work to work, depending on input images. Reply for b...

This paper presents a procedure for automating digital image analysis of cloud particle images recorded on video tape using the Cloudscope. 1 The Cloudscope is mounted on the wing of an aircraft and records cloud crystals as they impact the external lens and sublimate. The procedure presented breaks the analysis into several parts: frequency domain ltering, frame to frame movement correction, a...

The effect of enzymatic treatment on textiles has been investigated using standard texture algorithms. An extensive study in both the Fourier domain and the spatial domain has revealed the nature of the changes and resulted in one single feature that measures these changes in a fast and robust way.

The present study was carried out to determine some egg quality characteristics and storage related changes using computer assisted digital image analysis (CADIA) in an 18-month old moulted brown layer (Lohmann Brown) flock. A total of 150 newly laid eggs was randomly divided into two groups: eggs from the control group were broken immediately, while the remainder were stored at 18 C and 55% RH...

The focus of this article is on studying the descriptive proximity of manifolds in images useful in digital image pattern recognition. Extraction of lowdimensional manifolds underlying high-dimensional image data spaces leads to efficient digital image analysis controlled by fewer parameters. The end result of this approach is dimensionality reduction, important for automatic learning in patter...

For many Remote Sensing users, classification is the decisive stage of digital image analysis. Digital classification provides cartography and an inventory of the categories that are the object of study. In this paper we analyse a sector of the Natural Park of the Sierra de Mariola (Spain), with the aim of using two digital image classification procedures: supervised and unsupervised classifica...
