if higher image resolution, then the face detection chances is more? if image is so huge
According to my experience; I don't think so. We can do face detection/recognition with images of law resolution.
Dear sir,
In this article, They analyze reliability of the real-time system for face detection and recognition from low-resolution images, e.g., from video monitoring images. First, They briefly describe main features of the standards for biometric face images. Available scientific databases have been checked for compliance with these biometric standards. During the research we have considered both the correctness of extraction (location) of the face from the image as well as the correctness of the identification (based on the eigenfaces approach).

Hello!
In practice - face detection accuracy depends on detection algorithm. Each algorithm has its own lower limit of permissible resolution (for Viola-Jones, for example, bound depends on cascade minimum size), but has not upper bound of permissible resolution.
The resolution itself does not affect the face detection quality. A affects only in conjunction with the algorithm used.
We in our work reduced the resolution to increase productivity.Article Face tracking for a system of collecting statistics on visit...
