Abstract: A method of improving the resolution of a small moving object in a digital image sequence comprises the steps of: constructing (101) a high-resolution image background model, detecting (102) the moving object using the high-resolution image background model, fitting (103) a model-based trajectory for object registration, and producing (104) a high-resolution object description. The step of producing a high-resolution object description involves an iterative optimisation of a cost function (109) based upon a polygonal model of an edge of the moving object. The cost function is preferably also based upon a high resolution intensity description. The iterative optimisation of the cost function may involve a polygon description parameter and/or an intensity parameter.

Abstract: A method of detecting significant events intersecting a borehole from an image of the borehole wall having: (a) converting the image into a three-dimensional orientation space; (b) selecting a parameter relation that represents the intersection of an event (3,5 and 6) with the borehole wall; (c) creating a parameter space consisting of numbers as a function of the parameters, wherein each number is a measure of the support in the orientation space for an event characterized by the parameters that pertain to that number; (d) selecting in the parameter space a set of the largest numbers, wherein the parameters that pertain to each of these largest numbers represent the intersections of the significant events with the borehole wall; and (e) presenting the intersections pertaining to the set of the largest numbers as a list of data representing significant events.
