COLORIMETRY AND THE MULTICHANNEL IMAGE (DIGITAL IMAGE, REMOTE SENSING, COLOR GRAPHICS, INFORMATION PROCESSING, DISPLAY) | Posted on:1987-02-02 | Degree:Ph.D | Type:Dissertation | University:Texas A&M University | Candidate:JUDAY, RICHARD DAVID | Full Text:PDF | GTID:1478390017458172 | Subject:Engineering | Abstract/Summary: | | The use of color theory (particularly color metrics) is shown in the display of 2-D vector fields. Extant concepts in color theory are applied to data spaces to facilitate mapping from data into color. Novel color transformations are shown; one is a direct improvement over standard Landsat imagery, one is a means of showing in a single image the results of analyzing an image of arbitrarily large dimensionality, and another is an improved method of displaying geophysical attributes that reduces the number of separate displays by a factor of three. A new model for the inversion of a dot-matrix color machine is given. A method is formulated and demonstrated to convert a numerical image to halftone printed copy and avoid several color-contaminating physical steps previously necessary. Analysis of a differentiable color image machine by its Jacobian matrix is explored and then extended to discrete (non-differentiable) machines. Finally, an inverse problem is formulated--the extraction of quantitative information from color imagery, in the case of one principal continuous variable and subsidiary variables having lesser color impact. | Keywords/Search Tags: | Color, Image | | Related items |
