1. A system, comprising: a centroid rasterizer configured to receive original centroid data including a plurality of centroid intensity values and to form LC/MS images by assembling a portion of the centroid intensity values as a matrix according to retention time and mass/charge bin widths, wherein the centroid rasterizer is configured to determine a centroid integration range and a centroid mass/charge uncertainty and to determine the mass/charge bin widths based on at least one of the centroid integration range, the centroid mass/charge uncertainty, and a centroid uncertainty rate of change, wherein the centroid mass/charge uncertainty is based on a centroid uncertainty rate of change corresponding to a slope of a linear fit to centroid variation in a cluster of centroids with respect to a mean of a cluster mass to charge ratio; and an image processor configured to receive and merge the LC/MS images to form a merged image, the image processor further configured to segment the merged image reassembly.
