2021-08-03utils: raspberrypi: ctt: Fix namespace for sklearn NearestCentroid functionDavid Plowman
Starting in version 0.22, the NearestCentroid function is only available in the sklearn.neighbors namespace, when it was previously available in both the sklearn.neighbors.nearest_centroid and sklearn.neighbors namespaces. Use sklearn.neighbors as it works on all versions of sklearn.

2021-08-02utils: raspberrypi: ctt: Fix usage of findHomography functionDavid Plowman
The OpenCV findHomography function now raises an unhandled error if it receives fewer than 4 points whereas previously the limit was 3. This makes no material difference to the behaviour of the tuning tool as it will continue to search for the Macbeth chart at different scales.

2020-07-03utils: raspberrypi: ctt: json_pretty_print: Fix indentation handlingLaurent Pinchart
Indentation is handled by outputting spaces right after outputting a newline character. That works in most cases, but would result in the input '{}' being printed as { } instead of { } Fix it by outputting the indentation before outputting the next character after a newline. The indentation value will be updated by then.
