Presumably this will be done with AI.

This market resolves to the first year in which a computer program exists that can do the following:

• Take a photograph as input

• If the photograph is of food, estimate the total calorie count of all the food in the photograph

• The calorie count should be accurate to within +/- 10% of the true value

• The program should give a correct answer within the specified tolerance range above, on every 3 out of 4 runs of the program given substantially similar inputs.

Edit: Doesn't need to be able to pass the test for literally any kind of food, but should be able to reliably pass the above tests on common American dishes. If I can get it to personally work according to the above test on several different meals, this resolves yes.
