METHOD OF IMPROVING THE RESOLUTION OF A MOVING OBJECT IN A DIGITAL IMAGE SEQUENCE |
摘要 |
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. |
