get a classifier cascade parameters from original Cascase XML file

[DatNguyen97-VN]

Describe the feature and motivation

i'm looking for Viola-Jones Face Detection Algorithm on an FPGA but can't get classifier cascade parameters as rect0,rect1,rect2 (rectangle type) and strongthresh, weaksthresh or weakstagenum from original cascade.xml (haarcascade_frontalface_default.xml)

Additional context

i expect classifier cascade parameters as:

x_rect0.hex y_rect0.hex w_rect0.hex h_rect0.hex weight0.hex
...
...
weakstagenum.hex
strongthresh.hex
weakthresh.hex
left_tree.hex
right_tree.hex

Please help me find out method for this problem.

Thank you,
DatNguyen
