CanopyDigi Calculate

Program Overview
This program creates 12 sub-images from each false colour image that was chosen in ThresholdChoose to enable the calculation of percentage and dispersion data.

Buttons
Only two buttons are provided, “Start” and “End”, which do what they say.

Input
Input is from the CalculateToDo folder and this is automatic, requiring no user intervention.

Output
Output is to the CalculateDone folder and again this is automatic.

This output is twelve sub-images (BMPs) for each original false colour image selected in ThresholdChoose and stored in the CalculateToDo folder. Each new sub-image retains the name of the main false colour image with the sub-image information appended. So, for the main false colour image which was named Test001-th125blue0226989perc073p890.bmp, running CanopyDigi Calculate generates a series of sub-images starting with the existing name of Test001-th125blue0226989perc073p890 (without the .BMP ending) but adding “sq01blue21986perc085p883.bmp” (sq01 refers to the first square of the twelve calculated, blue21986 refers to the number of blue pixels (out of a possible 25,600) in that first square and perc085p883 refers to the percentage (85.883%)).

The information from these twelve sub-images is then combined to calculate the statistical output and is written to a similarly named text file.

Technical Comments
In addition, a single CSV (comma separated variable) file is constructed giving all necessary percentage and aggregation information for every original photograph analysed in a given run of the program. This can be loaded straight into a spreadsheet program (e.g. Microsoft Excel) or statistical software (e.g. SPSS or Minitab) for further analysis. Note that the user may need to effect a small amount of formatting (mainly of column widths), which cannot be done within CanopyDigi.

The text and CSV files are also copied to the CalculateHistoric folder. The computer NEVER deletes anything from this latter file, for safety reasons.
