Image processing system with image alignment mechanism and method of operation thereof

A method of operation of an image processing system comprising:

• identifying a feature point on a first image;
• determining a confidence threshold for updating the first image;
• determining a matching point on a second image, with the matching point corresponding to the feature point;
• dividing the first image and the second image using a grid having a grid-cell;
• identifying a cell population limit for updating the first image and the second image;
• calculating an offset component between the feature point and the matching point, with the offset component having a vertical offset and a confidence vector;
• identifying a correction field for adjusting the first image and the second image, with the correction field having a vertical adjustment, a zoom adjustment, a rotational adjustment, a keystone adjustment, or a combination thereof;
• updating the first image and the second image for minimizing the offset component and the confidence vector is greater than the confidence threshold, with the first image having a plurality of the feature point within the grid-cell and the second image having a further plurality of the matching point within the grid-cell, both pluralities exceeding the cell population limit;
• calculating an average in-cell displacement between a plurality of the vertical offset belonging to a further plurality of the feature point and the matching point within the grid-cell;
• and
• calculating an average grid displacement between a plurality of the average in-cell displacement from the grid-cell;
• and
• wherein:
• updating the first image and the second image includes minimizing the average grid displacement.
