摘要： A method of recognizing a character specifies a character in an image. Furthermore, the method of recognizing a character evaluates a symmetrical-ness of a shape of the character. Furthermore, the method of recognizing a character carries out an inclination correction process for the shape when the symmetricalness of the shape is detected.

摘要： The present invention includes an aqueous acidic chromate solution, suitable for forming colored chromate coatings on zinc-nickel alloy electrodeposits containing up to about 15% by weight nickel, which solutions have a pH within the range of about 1.3 to about 2.7, a hexavalent chromium concentration of at least 0.5 grams per liter, and preferably about 0.5 to about 100 grams per liter, and which contain sulfate in a weight ratio of SO.sub.4 :Cr.sup.+6 of about 0.025-1.5:1.The zinc-nickel alloy electrodeposits are preferably immersed in the chromating solution for a period sufficient to form the desired colored chromate coating. In some instances, a flash electrodeposit of zinc may be applied to the zinc-nickel alloy electrodeposit before it is immersed in the chromating solution. Alternatively, the zinc-nickel alloy electrodeposit may be immersed in the chromating solution and the solution electrolyzed, with the zinc-nickel alloy surface as the anode, at low current densities for a short period of time, after which, the electrolysis is discontinued and the zinc-nickel alloy surface is maintained in the chromating solution until the desired colored chromate film is formed.
