I need a mathematical formula to give a decision based on given situation :
in my issue, there is a decision must be taken based on the following values where :
- Total extracted feature Number in origin image is X , in my test example X is = (1496)
- Total extracted feature Number in object is Y , in my example Y is (273).
Now starting Matching Process ... then thereis a map function takes values from X and try to find matched features in object ... this function take a values called Z where Z is less than X ( must be) in my example Z = 381 ..
Now Z include two parts where
- N = noise features number where N. - M = real feature number where M in my example M= 134.
i would like to use a mathematical formula that give me a decision based on M value for example :
if score(M) for example > 0.25 then object is there otherwise not.
mu issue in every time when i changed image or object numbers are changes .. if i changed image X is changed , when i changed object Y is changed ..
I’m not familiar with mathematics formula but I would ask if log or others can applied
