Computational Complexity of Correlation in Time vs Multiplication in Frequency space
I am working with 2d correlation for image processing techniques (pattern recognition etc…). I was wondering if there is a theoretical approach on how to tell when to use multiplication in frequency space over correlation in time space. For sizes of 2x frequency space is obviously faster but how about small, prime sizes like e.g. 11?
Algorithm for deciding change in gesture
I am developing an application where I am taking dynamic gestures as input and then mapping them to keyboard controls. By dynamic gesture, I mean for example hand moving from left to right or hand moving right to left.
Stereo images rectification and disparity: which algorithms?
I’m trying to figure out what are currently the two most efficent algorithms that permit, starting from a L/R pair of stereo images created using a traditional camera (so affected by some epipolar lines misalignment), to produce a pair of adjusted images plus their depth information by looking at their disparity.
How to maintain standard quality of images uploaded by many users?
We’re developing a site where individuals (store owners) will be able to take pictures and upload to the site. Our biggest concern is the variance in quality of pictures across the site.
Getting started with object detection – Image segmentation algorithm
Just getting started on a hobby object-detection project. My aim is to understand the underlying algorithms and to this end the overall accuracy of the results is (currently) more important than actual run-time.
Effective and simple matching for 2 unequal small-scale point sets
I need to match two sets of 3D points, however the number of points in each set can be different. It seems that most algorithms are designed to align images and trimmed to work with hundreds of thousands of points. My case are 50 to 150 points in each of the two sets.

Is it possible to use any of the above solutions to compare incoming components to a gold standard image
Could any of the above solutions be used to compare a stuffed pcb to a gold standard picture. I am hoping to speed up the inspection process as well as improve accuracy.
Could this also be used as a inspection tool for individual components. Mainly size and labeling.
Text Image Binary Classifier without deep learning or tesseract
I have 20k small label images and each image has the word “Back” or “Front”.
