Abstract: Systems, methods, and apparatuses are described herein. For instance, a detection apparatus may comprise memory and at least one processor. The detection apparatus may be configured to obtain an image comprising at least one feature and a plurality of fiducials. The plurality of fiducials may be arranged in a pattern. The detection apparatus may be configured to determine a plurality of sub-regions of the image. Each sub-region comprises a subset of the fiducials comprised in the image. The detection apparatus may be configured to perform a geometric transform on each sub-region to generate a respective local transform associated with each sub-region. The detection apparatus may be configured to register respective locations of the fiducials comprised in the image based on the respective local transform associated with each sub-region. A size of each sub-region may be selected such that each sub-region is substantially invariant to stage jitter.
