physical properties of fruits and vegetables are the subject of many researches because of its importance in designing of agricultural machinery. banana fruit is one of important fruit. in this study some physical properties of banana fruit (cavendish variety) were determined. properties which were measured included weight of whole fruit peel and pulp weight, dimensions, surface area and projec...

in this work, cofe2o4 nanoparticles have been prepared by co-precipitation technique. the synthesized cofe2o4 nanoparticles were applied in the preparation of cofe2o4/polyacrylonitrile fiber nanocomposites by the electrospinning process. the prepared nanoparticles and nanofibers were characterized using the scanning electron microscopy (sem) and x-ray diffraction methods. the results manifested...

to determine the droplet characteristics of agricultural spray nozzles through water sensitive paper (wsp), the non-circular and overlapped spots appearing on the water sensitive paper surfaces are eliminated. in the conventional approach, the procedure is done according to the subjective self determined estimation of the operator. the objective of this study was to develop a practical alternat...

background: breast cancer is one of the most important diseases in females. malaysian women have not excluded. according to the malaysian oncology society [1], about 4% of women (who are 40 years old and above) have involved by breast cancer. masses and microcalcifications are two important signs for breast cancer diagnosis on mammography. according to our estimation, radiologists could diagnos...

This paper is concerned with the problem of recognition of objects laying on the sea-bed and presented on sonar images. Considering that high resolution sonar system provides acoustic images of high-quality, several researches have been interested in Synthetic Aperture Sonar (SAS) and Sides can sonar images for underwater objects. This work presents recent detection algorithms targeting their m...

This paper presents the comprehensive study of the various statistical measures and their application in digital image processing at root level. We have simulated the majority of statistical measures and reviewed their existing applications. Also we have explored and proposed their importance in some more research area of digital image processing. We have done their comparative analysis with th...

Segmentation is one of the basic steps for image processing. This paper enumerates and gives the comparative study of various image segmentation algorithms and their evaluation methods. Finally after a number of comparative experiments some valuable results are being given. Keywords-Image segmentation, edge detection, thresholding techniques, the evaluation of image segmentation.

anomaly detection (ad) has recently become an important application of hyperspectral images analysis. the goal of these algorithms is to find the objects in the image scene which are anomalous in comparison to their surrounding background. one way to improve the performance and runtime of these algorithms is to use dimensionality reduction (dr) techniques. this paper evaluates the effect of thr...

Image processing is a valuable tool in many areas, including medical image analysis, document processing and bioinformatics. However, designing good image operators requires deep knowledge in both image processing and the area of application, and the designed operator might not be the best possible. Automatic training of image operators allows people with little knowledge in Image Processing to...

This article aims to present the various applications of data compression in image processing. Since some time ago, several research groups have been developing methods based on different data compression techniques to classify, segment, filter and detect digital images fakery. It is necessary to analyze the relationship between different methods and put them into a framework to better understa...
