Title: | Optimizing optics and imaging for pattern recognition based screening tasks | Authors: | Lindblad, Joakim Sladoje, Nataša Malm P. Bengtsson E. Moshavegh R. Mehnert A. |
Issue Date: | 1-Jan-2014 | Journal: | Proceedings - International Conference on Pattern Recognition | Abstract: | © 2014 IEEE. We present a method for simulating lower quality images starting from higher quality ones, based on acquired image pairs from different optical setups. The method does not require estimates of point (or line) spread functions of the system, but utilizes the relative transfer function derived from images of real specimen of interest in the observed application. Thanks to the use of a larger number of real specimen, excellent stability and robustness of the method is achieved. The intended use is exploring the influence of image quality on features and classification accuracy in pattern recognition based screening tasks. Visual evaluation of the obtained images strongly confirms usefulness of the method. The approach is quantitatively evaluated by observing stability of feature values, proven useful for PAP-smear classification, between synthetic and real images from seven different microscope setups. The evaluation shows that features from the synthetically generated lower resolution images are as similar to features from real images at that resolution, as features from two different images of the same specimen, taken at the same low resolution, are to each other. | URI: | https://open.uns.ac.rs/handle/123456789/6959 | ISBN: | 9781479952083 | ISSN: | 10514651 | DOI: | 10.1109/ICPR.2014.572 |
