Moving objects detection, type recognition, and traffic analysis in video-based surveillance systems is an active area of research which has many applications in road traffic monitoring. This paper is on using classical approaches of image processing to develop an efficient algorithm for computer vision based on traffic surveillance system that can detect and classify moving vehicles, besides serving some other traffic analysis issues like finding vehicles speed and heading, tracking specified vehicles, and finding traffic load. The algorithm is designed to be flexible for modification to fulfill the changes in design objectives, having limited computation time, giving good accuracy, and serves inexpensive implementation. A 92% of success is achieved for the considered test, with the missed cases being abnormal that are not defined to the algorithm. The computation time, with a platform (hardware and software) dependent, the algorithm took to produce results was parts of milliseconds. A CNN based deep learning classifier was built and evaluated to judge the feasibility of involving a modern approach in the design for the targeted aims in this work. The modern NN based deep learning approach is very powerful and represents the choice for many very sophisticated applications, but when the purpose is restricted to limited requirements, as it is believed the case is here, the reason will be to use the classical image processing procedures. In making choice, it is important to consider, among many things, accuracy, computation time, and simplicity of design, development, and implementation.

Robot Vision is one of the most important applications in Image processing. Visual interaction with the environment is a much better way for the robot to gather information and react more intelligently to the variations of the parameters in that environment. A common example of an application that depends on robot vision is that of Pick-And-Place objects by a robotic arm. This work presents a method for identifying an object in a scene and determines its orientation. The method presented enables the robot to choose the best-suited pair of points on the object at which the two-finger gripper can successfully pick the object. The scene is taken by a camera attached to the arm’s end effector which gives 2D images for analysis. The edge detection operation was used to extract a 2D edge image for all the objects in the scene to reduce the time needed for processing. The methods proposed showed accurate object identification which enabled the robotic to successfully identify and pick an object of interest in the scene

Wavelet-analysis has become a powerful tool for denoising images. It represents a new way to achieve better noise reduction and increased contrast. Here, experimentally demonstrate abilities of discrete wavelet transform with Daubechies basis functions for improving the quality of noisy images.in this research two methods has been compaired for modify the coefficients using soft and hard threshold to improv the visual fineness of noisy image depend on Root-Mean-Square error (RMS). The low RMS value and better noise reduction find in soft threshold method which is based on Daubechies wavelet (db8) for first example image RMS=0.101 and second example RMS=0.109

This study was conducted for the purpose of monitoring changes in the marshes of southern Iraq, depend on image processing techniques for Landsat images for the period from 1990 to 2015.Landsat satellite images such as TM, ETM+, and LDCM for years 1990,2000, and 2015 in addition to set of maps were used, and then all these data were analysed and extracted the information from it by using ERDAS EMAGINE 2014 program also to extract the final maps layout the ARC GIS 10.2 program was used .Two important indices were extracted from satellite images, Transformed Normalized Difference Vegetation Index (TNDVI) and Normalized Difference Water Index (NDWI) for extract natural vegetation and water in study area. Supervised classification has been used to product three land cover maps for study area. After conducting all necessary analyses, the final results showed that the deterioration has happened largely in the waters of marshes and natural vegetation area in the period from 1990 to 2000 and then this deterioration was beginning decrease gradually and marshes began to recover from 2000 to 2015, there is increase in the surface area of waters of the marshes and natural vegetation in year 2015 than in year 2000, but this increase does not reach to the area of water and natural vegetation in year 1990.

Engineering and Technology Journal, 2016, Volume 34, Issue 3, Pages 497-512

This research proposed vision measurement system which consists of a camera carried on hand of a robot, which captured 2D image to the object from two sides with a constant distance of the objects. To achieve this work several experimental steps are needed: First step includes calibrating the camera by using a standard block to find the best distance between the camera and the object.The best result of a distance is (410)mm. The second step consists of using MATLAB 7.12.0 (R2011a) program to achieve image processing to get some digital information (number of pixels in each row and column), using the proposed line by line scanning algorithm, to extract 2D object dimensions. The resulted dimensions are found closer to real object dimensions that are measured using a digital vernier and 3d digital probe. Last step includes 2D image manipulating using the proposed algorithms to reconstruct the 3D objects depending on the resulted information (number of pixels).

Line Detection Using Radon Transform

H. H. Abbas; Hussein Ali Hussein

Engineering and Technology Journal, 2010, Volume 28, Issue 6, Pages 1267-1280

To extract features from digital images, it is useful to be able to find simple
shapes (straight lines, circles, ellipses, etc.).
In order to achieve this goal, one can be able to detect a group of pixels that are on
a straight line or a smooth curve. That is what a Hough transform is supposed to
do.
Since the Hough transform is a special case of Radon transform then line detection
process is accomplished using Radon transform.
In this paper, software for line detection using Radon transform has been designed
and implemented. Then the implemented software is tested under many conditions
and circumstances, the results are discussed, and many points are concluded from
the results.
