Determining rounding offset using scaling factor in picture resampling
An apparatus for coding video information according to certain aspects includes a memory and a processor. The memory unit is configured to store video information associated with a reference layer picture and an enhancement layer picture. The processor is configured to: store video information associated with a reference layer picture and an enhancement layer picture; receive a scale factor that indicates a proportion of scaling between the reference layer picture and the enhancement layer picture in a first direction; determine, without performing a division operation, a rounding offset value using the scale factor; and determine a coordinate in the first direction of a first sample located in the reference layer picture that corresponds to a second sample located in the enhancement layer picture using the scale factor and the rounding offset value.
