Top Forums Programming Base class's variables not accessible???? Post 302588587 by Corona688 on Monday 9th of January 2012 11:32:48 AM

Glad to see that my solution in the other thread worked for you. You might want to post that it worked in that thread, so people who find your thread through google know the solution worked. This forum exists for the benefit of everyone.

You're very close actually. You're not declaring the variables wrong, just using them in the wrong way.

If you want to use variables from a base class, even if you have access to them, you must still explicitly say they're in the base class. Like

Code:
Gsum = Sum<T>::x + Sum<T>::y + Sum<T>::z + Gx + Gy + Gz;

When I do this for all the Sum variables you access in GrandSum, your code works fine.

NAME
pgmtexture - calculate textural features on a portable graymap SYNOPSIS
pgmtexture [-d d] [pgmfile] DESCRIPTION
Reads a portable graymap as input. Calculates textural features based on spatial dependence matrices at 0, 45, 90, and 135 degrees for a distance d (default = 1). Textural features include: (1) Angular Second Moment, (2) Contrast, (3) Correlation, (4) Variance, (5) Inverse Difference Moment, (6) Sum Average, (7) Sum Variance, (8) Sum Entropy, (9) Entropy, (10) Difference Variance, (11) Difference Entropy, (12, 13) Information Measures of Correlation, and (14) Maximal Correlation Coefficient. Algorithm taken from: Haralick, R.M., K. Shanmugam, and I. Dinstein. 1973. Textural features for image classification. IEEE Transactions on Systems, Man, and Cybertinetics, SMC-3(6):610-621. BUGS
The program can run incredibly slow for large images (larger than 64 x 64) and command line options are limited. The method for finding (14) the maximal correlation coefficient, which requires finding the second largest eigenvalue of a matrix Q, does not always converge. REFERENCES
