A user-defined function capability is also available. TIN Interpolation tin Generate a triangulated irregular network TIN model from either iso line vertices or vector point input data using either a constrained or non-constrained Delaunay triangulation.
To accommodate quality of training signatures and width of classes, the user inputs the z-score at which fuzzy set membership decreases to zero. Topographic Thtorial slope Produce a slope gradient image from ideisi32 surface model.
Its primary role is in the development and revision of a knowledge base concerning a set of hypotheses.
Mean, gaussian, median, adaptive box, mode, standard deviation, Laplacian edge-enhancement, high-pass, Sobel edge detector and user-defined filters are accommodated. Set view direction, idrsii32 above the horizon and vertical exaggeration factor. Crosstabulate, crosscorrelate and calculate similarity statistics for image pairs. Mean, gaussian, median, adaptive box, mode, Laplacian edge-enhancement, high-pass, Sobel edge detector and user-defined filters are accommodated.

Full forward tutorixl backward transformations are accommodated using ellipsoidal formulas. Reference Guide Installation, system requirements, license terms, Clark Labs contact irisi32 product information. Hyperspectral Image Analysis hypersig Create hyperspectral signatures either by convolution of library spectral curves or by supervised signature extraction. Idrisi32 is fully COM compliant. Linear, quadratic and cubic mappings between the grids are provided, along with nearest-neighbor and bilinear interpolations.
For text symbol files, font, size, form and color may be changed.

Create documentation files for imported data. For polygon symbol files, outline color, fill type and color may be modified.
Nearest-neighbor and bilinear interpolations are supported. Note that the output image has the same sum ideisi32 probabilities as the original image on a per-category basis.

An image that expresses the degree of classification uncertainty about the class membership of the pixels is also produced. Non-rectangular regions can be analyzed by defining a binary mask. Graphic output includes cumulative or non-cumulative bar, line, or area graphs.
Fuzzy set membership is based on the standard distance of each pixel to the mean reflectance on each band for a signature.
Idrisi tutorrial explorer List, copy, rename, delete or move files. Dynamic and batch modeling is also supported.
Decision rules are recorded at each step and may be modified at any time. Modeling geometric and zonal anisotropy supported.

Maximum, minimum, normalized ratio and cover options are also tuorial. Tabulate errors of omission and commission, marginal and total error, and selected confidence intervals. The process uses polynomial equations to establish a rubber sheet transformation. Also compose X and Y component images into a force vector image pair. The iterative process makes use of a full maximum likelihood procedure. Up to input images can be analyzed as a group with the production of an equal number of resulting components.
Full SQL is supported. Tutoriial evidence maps are permitted so long as they are conditionally independent. Numeric output includes proportional and cumulative frequencies.
On-line Technical Support Link directly to the Clark Labs web site to fill out and submit a technical support problem report. What’s New in Release 2 An orientation to the new features of the system. Output includes trend surface images and surface statistics.
