摘要:
A method and system for cropping a digital image of multiple individual microarrays. Various embodiments of the present invention include, a digital image of multiple individual microarrays projected along a first coordinate axis by summing columns of pixel intensity values. A transformation maps the projected pixel intensity values to a transform in a frequency domain. A filter function is constructed from a power spectrum of the transform and multiplied by the transform to obtain a filtered transform. The filtered transform is mapped back to the spatial domain to give the filtered, spatial-domain image. The filtered, spatial-domain image is used to determine the coordinates of boundaries separating the individual microarrays along the first coordinate axis. The multi-pack of microarrays is rotated, and the method may be repeated for a second coordinate axis that is perpendicular to the first coordinate axis. The boundaries are used to identify the boundaries separating individual microarrays.
