Operations Useful for Similarity-Invariant Pattern Recognition
TLDR
Some ideas for position- and size-invariant two-dimensional pattern recognition lead, in some cases, to easily mechanized operations and an application to detection of straight lines is proposed.Abstract:

A review on image segmentation techniques
Nikhil R. Pal,Sankar K. Pal +1 more
TL;DR: Attempts have been made to cover both fuzzy and non-fuzzy techniques including color image segmentation and neural network based approaches, which addresses the issue of quantitative evaluation of segmentation results.
Journal ArticleDOI
A survey of thresholding techniques
TL;DR: This paper presents a survey of thresholding techniques and attempts to evaluate the performance of some automatic global thresholding methods using the criterion functions such as uniformity and shape measures.

A survey on image segmentation
King-Sun Fu,J. K. Mui +1 more
TL;DR: This survey summarizes some of the proposed segmentation techniques in the area of biomedical image segmentation, which fall into the categories of characteristic feature thresholding or clustering and edge detection.
Picture processing by computer
TL;DR: The field of picture processing by computer is reviewed from a technique-oriented standpoint and the processing of given pictures (as opposed to computer-synthesized pictures) is considered.

Fourier Preprocessing for Hand Print Character Recognition
TL;DR: A pattern-recognition method, making use of Fourier transformations to extract features which are significant for a pattern, is described and some considerations of the technical realizability of a fast preprocessing system for reading printed text are included.

Fourier Treatment of Optical Processes
TL;DR: In this article, the wave-number spectrum is defined as the complex conjugate of the n-dimensional Fourier transform of the weighting function, and the wave number spectrum of the flux distribution modified by any number of successive linear operations.

Optical Autocorrelation Measurement of Two‐Dimensional Random Patterns
Leslie S. G. Kovasznay,Ali Arman +1 more
TL;DR: In this paper, the autocorrelation coefficient of a function of two independent variables can be regarded as an image, and a novel optical technique is used to form another image.
