OBJECT DETECTION

3.3. ThresholdingAfter going through the procedure of module 2 inFigure 3, there are still some false blobs coming fromthe matching module. Thus, for each blob, a localthresholding method is applied to remove t hem usingcertain threshold values. For this experimental study,the threshold values are m[r]

training utilities, too. Once you have all your sets arranged the object images have to be “packed” into a vec-file in the folder “data”. This can only be done by the createsamples tool, even if you already have a set of object images and don’t want to generate artificial object[r]

The use of parts has several advantages. First, there are local spatial inter-actions between parts that can help with detection, for example, we expect tofind the nose right above the mouth on a face. Hence, we can exploit local partinteractions to exclude invalid hypotheses at a local level.[r]

The article deals with the detection of radar objects by exploiting the information on polarization based on the scattering matrix (SM) of the object.
