Methods for estimation of objects from an image

There is provided a method for estimating semi-transparent object(s) from an image comprising: receiving an image having semi-transparent and overlaid object(s) for estimation; calculating a probability map of the object(s), the probability map comprising multiple pixels corresponding to the plurality of pixels of the received image, wherein each probability map pixel has a value proportional to the probability that the pixel of the received image contains the object(s); calculating an approximation image of an object suppressed image based on the object probability map, wherein the approximation image is substantially equal to corresponding regions of the received image at portions with low probability values, and the approximation image denotes a smooth approximation of the image with the object(s) suppressed at portions with high probability values of the object probability map; and calculating the object(s) for estimation based on the calculated approximation of the object suppressed image.
