small typo here "use strict"

i think it may be better to have a more explicit name, and in english. It would be easier to understand for the user

Maybe something like haarcascade_converter.js and function convertHaarCascase(){}

if(!json['@type_id'] || json['@type_id'] != 'opencv-haar-classifier'){
return "this format is not valid!";
}
var res = [];

// Getting size
var parts = json.size.split(' ');
res.push(parseInt(parts[0]));
res.push(parseInt(parts[1]));

var stages = json.stages;

for(var i in stages){
// stage threshold
res.push(parseFloat(stages[i].stage_threshold));
// tree length
res.push(stages[i].trees.length)

// trees
for(var j in stages[i].trees){
var rects = stages[i].trees[j][0].feature.rects;
// getting tilted
res.push(parseInt(stages[i].trees[j][0].feature.tilted));
// getting rects count
res.push(rects.length);
for(var r in rects){
// removing dot in rects
rects[r] = rects[r].replace('.','');
parts = rects[r].split(' ');
for(var p in parts){
// getting rect itens
res.push(parseInt(parts[p]))
}
}
res.push(parseFloat(stages[i].trees[j][0].threshold))
res.push(parseFloat(stages[i].trees[j][0].left_val))
res.push(parseFloat(stages[i].trees[j][0].right_val))
}

}
return res;
}
