The image data is transformed in each processing step. The first steps, imaging, sampling and quantization, lead to digital images [32]. The imaging is commonly performed with physical devices transforming a band of the electromagnetic spectrum into an imaging function, which is then digitized ...

is f(x,y), then result image: Algorithm is applied to the whole image for the first-time. If the area of an object is strange, thresholding is done in that region and repeat the above steps until there are no object left to threshold. T y x f T y x f y x R , , 0 , , ...
operations, where all the pixel values in the imageare taken into consideration. Spatial domain processing methods includeall three types, but frequency domain operations, by nature of the frequency transforms, are global operations. Of course, frequency domain operations canbecome "mask operations," ...
A process for digital image processing, in particular for applications in the video monitoring field, comprises a step of detecting a first digital image and at least one second digital image. The process further comprises the steps of comparing the first and second digital images to detect at ...

), we can make use of the structural properties of the image to determine its location and estimate its structure. The coherency of and W over all the images can be exploited to solve the above problem with good accuracy. The steps followed to determine these values are: ...
