Latest Patents

Friman's latest patents include a method for generating a second object model based on a first object model for use in object matching. This invention involves a device and method that supports the generation of a second object model, which is crucial for object matching according to a specific algorithm. The first object model comprises object features of an imaged reference object, and it leads to the creation of sub-models that contain different sub-features of the original object features. Contribution indicators are provided for these sub-models, indicating how much each sub-feature contributes to incorrect matches. These indicators are based on matching the first object model and the sub-models with at least one model optimization image that contains predefined training features.

Another significant patent by Friman involves methods and arrangements for estimating one or more dominating orientations in a digital image. This method includes obtaining representative angles that represent the angles of gradient vectors for pixels in a part of the digital image. The process also involves calculating a target number of dominating orientations and obtaining sums based on computed sine and cosine factors for the representative angles. Ultimately, this leads to the
