AN APPARATUS FOR DETERMINING A CLASSIFIER FOR IDENTIFYING OBJECTS IN AN IMAGE, AN APPARATUS FOR IDENTIFYING OBJECTS IN AN IMAGE AND CORRESPONDING METHODS

摘要

An apparatus (100) for determining a classifier for identifying objects in an image is configured to receive a preliminary annotation (110) for pixels of the image, the preliminary annotation (110) comprising annotations for pixels to belong to an object or to background. The apparatus is further configured to transform the preliminary annotation (110) to an enhanced annotation (120), the enhanced annotation (120) further comprising at least one of annotations for pixels to belong to a transition between the background and an object, and annotations for pixel to belong to a transition between object. The classifier (130) is determined based on the enhanced annotation and a representation of the pixels of the image.
