C# Image Pattern Capture

I am in need of an engineer that can develop an application that will: Load a Color image Straighten image Crop the image to the remove background Locate a section of the item that contains a pattern that is repeated in the image with a % match accounting for both texture and color where the % match is a user specified value (I expect this value will be 90% or higher) The pattern size can vary on each item and is not known in advance. In the case where a match is found make a copy of the pattern section and save it to a file as a jpg In the case where a match is not found a log should list the top 3 best % matches found and location of regions Repeat the process for each file located in a directory The process can be slow running meaning that it can take up to 1 minute per item to analyse and select the pattern.
