A 2D Gabor wavelet filters the iris into multiple partitions know as __________.
Prescriptions for vision correction are given called diopters (D). Determine the meaning of the unit. Obtain information ( perhaps by calling an optometrist or performing an internet search) on the minimum uncertaintly with which corrections is diopters are determined and the accuracy with which corrective lenses can be produced. Discuss the source of uncertainties in both the prescription and accuracy in the manufacture of lenses.
The vernier scale of a travelling microscope has 50 divisions which coincide with 49 main scale divisions. If each main scale division is 0.5 mm, calculate the minimum inaccuracy in the measurement of distance.

- A hunter who is a bit of a braggart claims that from adistance of 1.6 km he can selectively shoot either of twosquirrels who are sitting ten centimeters apart on the same branch of atree. What’s more, he claims that he can do this without the aid of a telescopic sight on his rifl e. (a) Determine the diameter of the pupils of hiseyes that would be required for him to be able to resolve the squirrels asseparate objects. In this calculation use a wavelength of 498 nm (in vacuum) for the light. (b) State whether his claim is reasonable, and providea reason for your answer. In evaluating his claim, consider that the humaneye automatically adjusts the diameter of its pupil over a typical range of2 to 8 mm, the larger values coming into play as the lighting becomesdarker.
