1 HISTO_DOUBLE Histogram of an image as a function of another one HISTO_DOUBLE Computes the histogram of an image (Y_image) as a function of a sec- ond one (Z_image). This gives an information similar to, but slightly different from the cross histogram (cf HISTO_CROSS). The program computes histogram of the mean value and standard deviation. The result is a table of 4 Columns, in which 1) the first column contains the mean value of the Y_image (average of all pixels in the Y_image for which the Z_image value is included in the corresponding slot) 2) the second the standard deviation (of the Y_image values). 3) the third the number of pixels of the Y_image used to compute the mean and deviation. 4) the fourth column contains the histogram abscissa (actual value of the input Z_image) 2 Z_NAME\$ TASK\FILE "First input image" Z_NAME\$ This is the name of the input image that defines the histogram slots. 2 Y_NAME\$ TASK\FILE "Second input image" Y_NAME\$ This is the name of the input image that defines the histogram values. 2 Y_BLC\$ TASK\INTEGER "Bottom left corner" Y_BLC\$[4] This is the position (in pixels) of the Bottom Left Corner of the part of both maps that will be used to compute the histogram. 2 Y_TRC\$ TASK\INTEGER "Top right corner" Y_TRC\$[4] This is the position (in pixels) of the Top Right Corner of the part of both maps that will be used to compute the histogram. 2 X_BIN\$ TASK\INTEGER "Number of histograms bins" X_BINS\$ This is the number of histogram slots that will be defined within the values of the first image. 2 X_MIN\$ TASK\REAL "Minimum value" X_MIN\$ This is the value (of the first image) corresponding to the lowest bin. 2 X_MAX\$ TASK\REAL "Maximum value" X_MAX\$ This is the value (of the first image) corresponding to the highest bin. 2 X_NAME\$ TASK\FILE "Output histogram name" X_NAME\$ This is the name of the output histogram. 1 ENDOFHELP
