Mathematical morphology is an implement for extracting image components that are helpful in the demonstration and explanation of region shape, boundaries, skeletons, and convex hull. Morphological operations are used in pre and post processing for thinning, filtering. Morphology is a development method used to extract image meaningful. In this paper, study the different morphology methods that ...

In this work an automated traffic analysis in aerial image sequences recorded by an unmanned aerial vehicle (UAV) has been developed, which provides the trajectories of the vehicles especially during overtaking. Methods of photogrammetry and image processing are used to detect the vehicles and to determine and track their positions. Camera calibration is necessary in order to transform image co...

one of the most fundamental features of digital image and the basic steps in image processing, analysis, pattern recognition and computer vision is the edge of an image where the preciseness and reliability of its results will affect directly on the comprehension machine system made objective world. several edge detectors have been developed in the past decades, although no single edge detector...

as the information carried in a high spatial resolution image is not represented by single pixels but by meaningful image objects, which include the association of multiple pixels and their mutual relations, the object based method has become one of the most commonly used strategies for the processing of high resolution imagery. this processing comprises two fundamental and critical steps towar...

In this paper, we present an adaptive Gerchberg-Saxton algorithm for phase retrieval. One of the drawbacks of the original Gerchberg-Saxton algorithm is the poor results it yields for very bright images. In this paper we demonstrate how a dynamic phase retrieval approach can improve the correlation between the required image and the reconstructed image by up to 10 percent. The paper gives expli...

here are several domain transform like Fourier, sine, cosine and wavelet transform to processes an image. But the problem with these transform are inefficient to solve certain problem. Fractional Fourier transform gives extra degree of flexibility. It helps to improve image such as Image sharpness, filter and watermark. Keywords— Image processing, Fractional Fourier transform, FrFT, Image blurr...

he fundamental arrangement of granular behavior is important to know about the soil stability and influence the design of structural foundations. The structural stability is particularly useful in earthquake events. Therefore, to work on measuring the arrangement and orientation of an assemblage of granular particle is essential. In this paper, we evaluate the porosity of the given sand images ...

--In this paper, an improved edge detection method which computes image edges using the concept of Sobel Operator with Center of Mass method is presented. The proposed method can be used as framework for multi-scale edge detectors in image processing. Here the edge detection by Sobel Operator with Center Of Mass method is compared with simply COM method. Keywords--Edge detection, Sobel operator...

this paper gives the idea about lip reading. Generally image processing is done to process an image for different application. There is variety of transform base feature extraction method. Visual recognition system or lip reading method is important generally in noisy condition. The new modality in image processing area is gives you dictation of voice. Keywords— ANN (Artificial Neural Network),...
