My app gives access to the inside of famous landmarks using image recognition to determine who is inside and made bookings using our app. It also acts as a recommendation tool that helps determine relevant places to visit and why based on variables set by users from experience.
Here is a simple thought to ponder: if the landmark is famous, is image recognition of people (with all the ethical issues that brings) necessary to promote it? What value does the image recognition bring that simple user documentation (i.e. user supplied data and imagery) would not?
As a marketing consultant to tourism, health, robotics and HR startups, I look at what people are asking for, and what minimum tech application is necessary to provide it.
Consider this - does your image recognition better serve the 'hidden gems' of tourism?
Happy to discuss further :)
