Embodiment Construction

[0106] A digital or digitized image is formed by an array of pixels P(n,m), where n,m=1,...,N. Individual pixels are small dots that have a certain appearance on a monitor or screen or on printed paper. The appearance of the points can be represented by numerical data. In a so-called grayscale image, each point has a certain brightness corresponding to a certain gray level in the grayscale. In color images, more parameters are usually necessary in order to adequately describe the appearance of the pixels by numerical data. Several systems have been defined for univocally representing the appearance of pixels in color images. One possible system is the so-called and well-known HVS (Hue, Vitality, Saturation) or the so-called RGB (Red, Green, Blue) system. Since it is obvious to a person skilled in the art that these values ​​have to be replaced by corresponding numerical data if color images are processed, in the present simplified example only the intensities I(n,m) have be...

Abstract

A method for coding pixels or voxels of a digital or digitalized two dimensional or three dimensional image, comprises the steps of: providing a digital image consisting in a two dimensional array of pixels or in a three dimensional array of voxels, each pixel or voxel being defined by at least one variable as its intensity in a grey scale image or the HSV (Hue, Saturation and Value) or the RGB values in a colour image; each pixel or voxel of the image being considered as a target pixel or voxel and for each target pixel or voxel a neighborhood being formed by a pixel or voxel windows comprising the said target pixel or voxel and a certain number of surrounding pixels or voxels for each target pixel or voxel generating a vector univocally associated to the said target pixel or voxel, the components of the said vectors being generated as a function of the values of the said target pixel or voxel and of each of the pixels or voxels of the said pixel or voxel window. The function of the values of the said target pixel or voxel and of each of the pixels or voxels of the said pixel or voxel window correspond to the characteristic parameters of the numerical matrix representing the pixels or voxels of the said window or of a transformation of the said numerical matrix. The invention relates also to an image processing method in which image data coded according to the above method are processed by means of a predictive algorithm as for example an artificial neural network.

Description

technical field [0001] A method of encoding pixels or voxels of a digital or digitized image and a method of processing a digital or digitized image, in particular identifying features of an imaged object to which said method of encoding pixels or voxels is applied. [0002] The invention relates to a method of encoding pixels or voxels of a digital or digitized two-dimensional or three-dimensional image, comprising the steps of: [0003] a) Provide a digital image constructed as a two-dimensional pixel array or a three-dimensional voxel array, by at least one variable, such as intensity (intensity) in grayscale images or HSV (hue, saturation, and purity) or RGB in color images Values ​​to define individual pixels or voxels; [0004] b) using each pixel or voxel of the image as a target pixel or voxel, and, for each target pixel or voxel, by including the target pixel or voxel and a certain amount of surrounding pixels or voxels Or the voxel window forms a neighborhood (neig...
