Abstract: In some examples, a print cartridge includes a memory device comprising quantized coefficients derived from a lossy compression, at a selected step size, of a difference color table including a plurality of difference nodes in which each difference node represents a difference value that is a difference of a value of a node of a color table and a value of a corresponding node of a reference table, the quantized coefficients useable to produce a reconstructed difference color table including a first set of difference nodes each representing a difference value that is within an error threshold at the selected step size, and a second set of difference nodes each representing a difference value that is outside an error threshold at the selected step size. The memory device further comprises corrective information to correct the second set of difference nodes of the reconstructed difference color table.

Abstract: In an example, a method is described that includes dividing an input image into a plurality of strips, where each strip is smaller than a whole of the input image. A plurality of binary images is then generated, where each of the binary images corresponds to one of the strips. Connected component labeling is performed on the binary images, one binary image at a time. An object map for the input image is then generated based on the results of the connected component labeling.

Abstract: A memory device includes a compressed color table and corrective information. The compressed color table includes a first set of nodes of the color table compressed with a lossy compression at a selected compression ratio. The first set of nodes include a color difference within an error threshold at the selected compression ratio. Corrective information is included for a second set of nodes of the color table. The second set of nodes have a color difference outside the error threshold.

Abstract: A μPAD may include a substrate comprising a substrate. The μPAD may further include a non-polar material printed on a surface of the substrate such that a portion the surface is exposed. The exposed portion may include a receiving area, a plurality of test areas, and a plurality of channels disposed between the receiving area and the test areas. The μPAD may further include colorimetric sensors respectively positioned in the test areas. The channel regions may be configured to receive an analyte solution from the receiving area and direct the analyte solution to the colorimetric sensors. A system may perform image processing on captured images of the μPAD to provide multiplexed analysis of analyte solutions applied to the μPAD.
