The main question that provoked the following series of papers was: How a structural object model should depend on the available routines of low-level processing?
“Robust Identification Based on a Processing-Oriented Object Representation”(with F.Macías-Rangel and H. Moncayo) in Intelligent Robots and Computer Vision XX: Algorithms, Techniques, and Active Vision, D. P. Casasent &E. L. Hall, Eds., Proceedings of SPIE, Vol. 4572, 2001.
"Structural Matching to Control the Low-Level Processing" , (with F. Macias-Rangel), in Proc. of Congreso International De Computación , CIC2000, 13-17 November 2000, IPN, Centro de Investigación en Computación, Mexico, pp. 273-284, 2000.
"Knowledge-Based and Processing-Oriented Object
Representation" (with F. Macias-Rangel), in Proceedings
of the Workshop AAPR'2000: Advances in Artificial Perception and
Robotics, Eduardo Bayro Corrochano (Ed.), M-00-26 (CC/CIMAT), Guanajuato,
Mexico, pp. 151-158, 2000.
" Detector-Based Visual Identification of Known Objects ", in Enhanced and Synthetic Vision 2000, J.G. Verly, Ed., Proceedings of SPIE, Vol. 4023, pp. 269-279, 2000.
Three new issues are presented in them (i) A formalization of low-level processing (ii) A new object representation (TSG-model) for Pattern Recognition (iii) A new image processing scheme for verification if an input image contains an object corresponding to a given TSG-model. The peculiarity of the processing is that its part representing low-level image processing works under full control of typical AI search interacting with the TSG-model of object to be identified.
In other words, structural identification is reduced in the papers to AI search that manipulates with two kinds of feasible block-operations, the one represented by detectors (this is a formalization of low-level image processing) and the one represented by operations with sets (union, intersection, etc.) of image frame.
The most recent paper of this set extends the technique for the case of possible occlusions and omission of details during detection.
· Papers related to Intelligent
The ideas developed in the following set of papers, perhaps, are of common interest. In particular, they are related to a challenging application: Planning via Internet a fastest trip by means of all available timetables of all kinds of transport.
The problem of robot navigation is represented in those papers as an extension of well known shortest path problem on graphs. Then, an efficient resolution for this extended problem is presented. For robotics, this approach leads to a new graph-based representation of its environment. It gives a new point of view about robot learning, perception, and other parts of robot architecture and suggests a new research program for them.

The original goal was a one-step extraction of "something one-dimensional in picture, disregarding irrelevant details". It led to a generalization of edgel. "The 3-Frequencies Method" (3FM) was developed for that purpose in

In the following two papers 3FM was applied to a next step generalization of edgel, and also to extraction of "something 0D".
