An Approach To Nonlinear Mapping For Pattern Recognition, Nguyen Duong, L. I. Ruh-Ming, Daryl B. Simons Jan 1979

An Approach To Nonlinear Mapping For Pattern Recognition, Nguyen Duong, L. I. Ruh-Ming, Daryl B. Simons

LARS Symposia

Nonlinear mapping has been used in the past for data structure analysis. Many interesting heuristic approaches to map n-dimensional data to a lower dimensional space such that the local structure of the original data is reserved have been proposed by Kruskal, Sammon, and others. Basically, a criterion for local structure preservation is first defined, then a new data configuration is obtained by an iterative process to minimize the selected criterion.


Computer Recognition Of Citrus Infestations, D. H. Williams, J. K. Aggarwal Jan 1979

Computer Recognition Of Citrus Infestations, D. H. Williams, J. K. Aggarwal

LARS Symposia

A computer software system is described that uses digitized color information from aerial color infrared transparencies to detect the a presence of citrus mealybug (Pseudococcus citri Risso), brown soft scale (Coccus hesperidum L.), and Rio Grande gummosis in individual citrus trees. The color coordinates at each spatial point, and color differences at adjacent points are used to locate the trees and to detect the infestations; and compensation is made for the variation in color characteristics between different transparencies. The system requires the input of four parameters: a flag denoting the presence of heavy shadows in the image, nominal tree size …


An Interactive Color Display System For Labelling Crops, Toyohisa Kaneko, Linda K. Moore, Robert T. Smart Jan 1979

An Interactive Color Display System For Labelling Crops, Toyohisa Kaneko, Linda K. Moore, Robert T. Smart

LARS Symposia

To perform classification on remotely sensed imagery data, a small number of pixels or fields need to be labelled. It has been found that this labelling task requires many auxiliary materials such as crop calendar, soil data, cropping practice and a weather summary. This task is at the present time manually performed by photo-interpreters. It is time-consuming and liable to human error. The paper describes a computer based interactive color display system for assisting photointerpreters. Its objective is to reduce contact time and to increase labelling accuracy. This system has been designed to extract features from a temporal series of …
