Abstract:
A method and apparatus for determining an output value representing a picture data by applying a piece-wise linear function on an input value representing a picture data, said piece-wise linear function comprising at least one piece characterized by a slope value ai, an offset value and an interval defined over a range of values comprised between a lower bound and an upper bound. The method comprises: —obtaining ( 50 ) a coded input value X coded with quantization on n bits; —obtaining ( 51 ) a coded slope value Ai, said coded slope value Ai representing a mantissa value ai_m coded with m bits and an exponent of 2 value ai_e coded with (K−m) bits, K being the total number of bits to code said slope value ai; —identifying the (K−m) most significant bits of the coded slope, said (K−m) most significant bits forming an exponent value ai_e of a decoded slope value; —identifying the m least significant bits of the coded slope value, said m least significant bits forming the mantissa ai_m of the decoded slope value; —determining ( 52 ) the output value y by shifting the product of the mantissa ai_m of the decoded slope and the coded input data X by an integer value equal to (n+m−ai_e−p).

Claim (Index 11):
The apparatus of  claim 10 , wherein said meand for obtaining a coded slope value A i  are configured to obtain the coded slope value Ai by coding the slope value a i  by A i =Int(a i *(1<<n)) when the slope value ai<1, and by A i =Int((1/a i )*(1<<n)) when the slope value ai>1; and the apparatus further comprises means for:\n signaling whether the slope of the first interval is lower than or greater than 1; signaling the ending point of a current interval when:\n the slope of a following interval become greater to 1 and the slope of the current interval is lower than 1; or \n the slope of a following interval become lower than 1 and the slope of the current interval is greater to 1.
