Shadow Detection from rgb video strem

Hi everyone,

I need help in this code that I wrote in shadow detection but the function is stoping in the (IF)

and send the message

Operands to the || and && operators must be convertible to logical scalar values.

Error in ziad (line 46)

if( w>=alphaV || w<=betaV || sat<=-0.3 || hue <=0.2)
