c++ - Kinect depth pixel -


i working on kinect project using ms kinect sdk1.7. when trying sample code bridging opencv. not understanding code of calculation // convert depth info intensity display byte b = 255 - static_cast(256 * realdepth / 0x0fff);

and how can pixels mat depth distance?

i'm not familiar kinect, line i'm assuming realdepth depth measured device inside kinect, in si unit (since 0x0fff 4096 i'm assuming mm). line there 

// convert depth info intensity display  byte b = 255 - static_cast(256 * realdepth / 0x0fff);

then converts depth value in mm range (0 - 255) can displayed on monitor screen.

you don't need depth 'back', can use realdepth directly

when creating stub in ocmockito, use calls stub out method calls , return values: [given([stubobject mymethod]) willreturn:somevalue]; the problem have if don't define method method gets called during test, default seems to return nil . can lead sneaky bugs since real methods asserted never return nil , therefore return value not tested in code calling method. is there way change default behavior or maybe test if called on object apart few methods i'm stubbing? no, ocmockito stubs "nice". if want "strict" stubs, ocmock may suit better.
