[Rtftr-devel] Saving cascade in Opencv

[Anjan <roc...@gm...>]

Hi Bibek,
the coding of adaboost is complete, and i think it's selecting features
wisely. Now we should move on to creating the cascade. We need to discuss on
how we save the overall cascade in the disk.
Here is what i have in mind.

* in one file, save the number of stages in the cascade. ( eg.
stagecount.xml)
* in other file, the threshold of each stage will be saved ( eg. cvMat*
stagethreshold = cvCreateMat( no. of stages, 1, CV_32FC1)
* in other files, the classifiers of one stage will be saved (eg.
stage_1.xml stage2.xml etc)

So, during detection this is what we will do

* first load stagecount.xml
* read threshold file
* create array of the matrices of size no. of stages and load all the stages
in this array.

I think for continuing the cascade generation also, this will be ok. We'll
include a flag (continue = 0/1) to cascadegeneration() function and if
continue=1, we continue the cascade generation process by loading the
stagecount.xml, thresholds, stages and then creating new nonfaces and
continuing.

Reply soon.
