https://community.intel.com/t5/Intel-Integrated-Performance/Optical-Flow/m-p/884969#M10664 <P>I am using the OpticalFlowPyrLk to track some point in an image. I know that the input point list is a set of floating point values. I normal use floating point values with no decimal part as the input (e.g. 125.00). If I use an input value with a decimal part (e.g. 125.639), can I expect to get a correct displacement based on that decimal part, or is the value truncated to an integer part before the calculations are done?</P> Thu, 11 Dec 2008 00:33:55 GMT robert_p_higgins 2008-12-11T00:33:55Z https://community.intel.com/t5/Intel-Integrated-Performance/Optical-Flow/m-p/884969#M10664 <P>I am using the OpticalFlowPyrLk to track some point in an image.
