In this study, ZnFe2O4 nanofibers were fabricated by facile electrospinning method and subsequent calcination process. The scanning electron microscopy (SEM) images showed that ZnFe2O4 nanofibers which were in diameters of 30-100 nm and consisted of nanograins had typical morphologies of spider nets.

The paper "Image processing-based automatic gradation of stone aggregates" aims to employ image processing methods to develop a simple tool for automatic gradation of stone aggregates. The methods of image thresholding, Gaussian filtering, median filtering, morphological closing, and contour analysis are employed. The output of the newly constructed system is the plots demonstrating particle size distribution. These plots can be used for further inspection of aggregate gradation. The system has been developed in Python and with the help of the OpenCV library.

The final product was characterized by IR, Raman and XRD spectroscopic methods illustrating the presence of pure α-Fe2O3. SEM images of this material revealed a homogeneous morphology of microcube Fe2O3 with a size of about 500 nm. The catalytic activity of cubic Fe2O3 was investigated on the degradation of methylene blue in a heterogeneous Fenton system.

In this paper we chiefly accentuation on the color/shade of the activity sign for its recognition on the grounds that in many spots a standard arrangement of hues are utilized as a part of movement sign like red is used in prohibition signs. In the directional signs blue is the foundation shading in the directional signs and yellow is chosen for warning signs.

Recently, the innovative vein finder system has been studied extensively and has many practical uses in healthcare and security. Developing a better vein finder system often relies on image processing procedures which help to enhance the vein images. Conventional image processing procedures as median filtering and adaptive histogram equalization have shown benefit in enhancing vein patterns. However, in some cases when there are hairs present in the images, most of these procedures are less effective in removing noises from hairs.

Aging is characterized by a gradual breakdown of cellular structures. Nuclear abnormality is a hallmark of progeria in human. Analysis of age-dependent nuclear morphological changes in Caenorhabditis elegans is of great value to aging research, and this calls for an automatic image processing method that is suitable for both normal and abnormal structures.

Multiplexed in-situ fluorescent imaging offers several advantages over single-cell assays that do not preserve the spatial characteristics of biological samples. This spatial information, in addition to morphological properties and extensive intracellular or surface marker profiling, comprise promising avenues for rapid advancements in the understanding of disease progression and diagnosis.

Handling and improving the quality of medical images with the help of computer software is one of the important stages in the diagnosis and treatment. In this article, we focus on describing the new morphological algorithms by ITK (Insight Segmentation and Registration Toolkit). These morphological operators eliminate noise, detect good edges, and overcome the drawback of traditional edge detection methods.

This acoustic imaging has identified a canyon system at the slope and a shallow marine fan, which contains shelf incisions extending the İstanbul Strait incision. Multibeam bathymetry, ultra-high resolution seismic profiling and coring correlations on this subaqueous fan area allowed reconstruction of morphology and patterns of sediment distribution indicative of high energy sediment transport processes.

This paper is intended as an overview of recent developments and trends. It wishes to pro- vide a short survey of the principal families of approaches, their use and limitations. Algo- rithms generic or specific to particular imaging modalities are not given here (see for exam- ple (10)). Section 2 presents the analysis pipeline, which accepts as input raw data and provides some form of processing or interpretation. Two basic processing paradigms are summarized in section 3, namely linear (or pseudo-linear) and morphological.
