Abstract: Embodiments of the invention relate to a method for determining that an object in a sequence of images is a human. The method may include the steps of detecting an object in a first image from the sequence of images and assigning a first score to the object. The object is tracked to a second image from the sequence of images and a second score is assigned to the object in the second image. The second score is compared to a threshold that is inversely related to the first score and a determination that the object in the second image is a human is made based on the comparison.

Abstract: A positive-working, ablation-imagable lithographic printing plate precursor can be imaged and used for lithographic printing without wet processing. This precursor has a sulfuric acid or phosphoric acid anodized aluminum-containing substrate, a crosslinked hydrophilic inner layer comprising a crosslinked polymer derived by using a crosslinking agent that comprises at least two aldehyde groups, and an acidic compound. Over the crosslinked hydrophilic inner layer is an oleophilic outer layer comprising an infrared radiation absorber and an oleophilic polymer. The precursor also has a copolymer comprising randomly recurring units derived from each of a (meth)acrylamide and vinyl phosphonic acid. This copolymer is present either within the crosslinked hydrophilic inner layer, as part of a different copolymer layer between the crosslinked hydrophilic inner layer and the substrate, or in both places.

On this, a crosslinked hydrophilic inner layer is formed using a formulation comprising: (1) a hydrophilic polymer having recurring —CH2—CH(OH)— units, (2) a crosslinking agent for these units having at least two aldehyde groups, and (3) an acidic compound. An oleophilic outer layer formulation comprises: (a) an infrared radiation absorber, and (b) an oleophilic polymer having at least 10 mol % randomly recurring —CH2—CH(OH)— units, within an organic solvent solution, and dried to form a composite structure. The composite structure is heated so its surface exhibits less than 10% optical density change within a first rectangular area (width W1 and length L1) centered inside a second rectangular area (width W2 and length L2), where the surface is subjected to 1000 rubs according to ASTM D3181 using the organic solvent solution.
