The entire image is divided into pixels, the size and shape of which depend on the size and shape of the capacitors. Sampling determines the geometric properties of an image.b) Quantizationi. It assigns the intensity value to a pixel and defines the radiometric properties of the image (Schenk, 1999) From the application point of view, the digital image appears as a matrix I composed of r = 1, and so on, R are lines ej = 1 and so on, C are columns. For this, the elements of the matrix that carry intensity values. In this way, depending on the type of image, the matrix will be composed of a single layer (an image in gray tones) or multiple layers (colored, multispectral and hyperspectral images). A color chart is an alternative form of describing an image. Figure 2.1 This figure shows image sampling data from an aerial photograph. (Norbert Haala, 2009)2.2.1 Orientation and georeferencingDetermining the object coordinates of measured points in images is a fundamental task of photogrammetry. The geometric relationship between an image and an object coordinate system known as the central projection. This is analytically what is described by collinearity
