White balance

White balance (or WB) is necessary in digital cameras because light doesn’t just vary in brightness but also in ‘colour temperature’. The human eye naturally adjusts for this (making a sheet of white paper appear white no matter what the lighting conditions) but the camera requires WB to compensate for these different conditions. 252 more words

Operation-semantics implementation - recursion and evaluation

I’ve been struggling while implementing simple semantics. Here is my code:

isRewritable:=(Or]=!=oneStepRewrite,e==={}]);
(* !!!this is what is obviously wrong!!!
oneStepRewrite[x] := {};
oneStepRewrite := {};*)

(* Derivative Number *)
oneStepRewrite]:={0};
(* Symbol - "x" *)
oneStepRewrite]:={1};
(* Addition - "plus" *)
oneStepRewrite] := {e};
oneStepRewrite] := {e};
oneStepRewrite] := {n + m};
oneStepRewrite] := Join[
   Map&, oneStepRewrite[e]],
   Map&, oneStepRewrite[f]]
 ];

(* Times *)
oneStepRewrite] := {e};
oneStepRewrite] := {e};
oneStepRewrite] := {0};
oneStepRewrite] := {0};
oneStepRewrite] := {n * m};
oneStepRewrite] := Join[
   Map&, oneStepRewrite[e]],
   Map&, oneStepRewrite[f]] 
];

(* Derivation - "derivative" *)
oneStepRewrite]] := {plus, derivative[f]]};
oneStepRewrite]] := {plus], times, f]]};

(* Lists Mapping *)
oneStepRewrite := Union&, l]]];
