Accuracy and average speed comparison between some famous face ...
Efficient face detectors with low computational cost and fast speed are still a pressing problem despite the significant progress made in uncontrolled face detection.
We investigated whether there was a relationship between famous faces RTs and accuracy , i.e., some faces could have been recognized faster with high accuracy and others slower with low accuracy .
How Fast is Famous Face Recognition
We investigated whether there was a relationship between famous faces RTs and accuracy , i.e., some faces could have been recognized faster with high accuracy and others slower with low accuracy .
In the second experiment, 101 participants performed a highly time constrained recognition task using the Speed and Accuracy Boosting procedure. Results indicate that the fastest speed at which a face can be recognized is around 360-390 ms.
How Fast is Famous Face Recognition
The results show that, despite the use of speed constraints, subjects were slow when they had to categorize famous faces : minimum reaction time was 467 ms, which is 180's more than during superordinate categorization and 160'ms more than in the gender condition. The rapid recognition of familiar faces is crucial for social interactions. However the actual speed with which recognition can ...
In previous individual differences studies, the speed (measured in easy tasks) and accuracy (difficult tasks) of face cognition (FC, involving perception and recognition of faces ) have been shown to form distinct abilities, going along with divergent factorial structures. This result has been replicated, but remained unexplained.

The rapid recognition of familiar faces is crucial for social interactions. However the actual speed with which recognition can be achieved remains largely unknown as most studies have been carried out without any speed constraints. Different paradigms have been used, leading to conflicting results, and although many authors suggest that face recognition is fast, the speed of face recognition ...
Assessment and Estimation of Face Detection Performance Based on Deep ...
Additionally, we train a model that is able to predict for unseen images, the performance metrics (in terms of accuracy and speed ) that the end-user could expect based on the given face detection method, specific hardware, image size and percentage of image resizing.
Rapidly recognizing familiar people from their faces appears critical for social interactions (e.g., to differentiate friend from foe). However, the actual speed at which the human brain can distinguish familiar from unknown faces still remains debated. In particular, it is not clear whether familiarity can be extracted from rapid face individualization or if it requires additional time ...
