$\%$

$\%[$out$,$F$]=$myhisteq$($in$,$L$)$;

$\%$

$\%$ My histogram equalization function

$\%$ Takes an L level input image $\text{'}$in$\text{'}($must be integers$)$

$\%$ and maps it to an L Level output

$\%$ with an approximately flat histogram.

$\%$

$\%$ out equalized image $($L levels$)$

$\%$ F mapping function

$\%$ in input image $($L levels, integer values$)$

$\%$ L # levels in input image
