| 20080212887 | Method For Coding Pixels or Voxels of a Digital Image and a Method For Processing Digital Images - 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 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. | 09-04-2008 |
| 20100135544 | Method of registering images, algorithm for carrying out the method of registering images, a program for registering images using the said algorithm and a method of treating biomedical images to reduce imaging artefacts caused by object movement - In a method for registering biomedical images such as at least a first and a second digital or digitalized image or set of cross-sectional images of the same object, within the first image or set of images a certain number of landmarks, so called features are individuated by selecting a certain number of pixels or voxels. The position of each pixel or voxel selected as a feature is tracked from the first to the second image or set of images by determining the optical flow vector from the first to the second image or set of images for each pixel or voxel selected as a feature. Registration of the first and second images or set of images is carried out by applying the inverse optical flow to the pixels or voxels of the second image or set of images. The invention provides for an automatic trackable landmark selection step consisting in defining a pixel or voxel neighbourhood around each pixel or voxel of the first image or first set of cross-sectional images; for each target pixel or voxel determining one or more characteristic parameters which are calculated as a function of the parameters describing the appearance of the said target pixel or voxel and of each or a part of the pixels or voxels of the window and as a function of one or more characteristic parameters of either the numerical matrix or of a transformation of the said numerical matrix representing the pixels or voxels of the said window. The pixels or voxels coinciding with validly trackable landmarks are determined as a function of the said characteristic parameters of the target pixels or voxels. | 06-03-2010 |
