Title: SYSTEMS AND METHODS OF ADAPTIVELY DETERMINING TEMPLATE SIZE FOR ILLUMINATION COMPENSATION
Abstract:
Techniques and systems are provided for processing video data. For example, a current block of a picture of the video data can be obtained for processing by an encoding device or a decoding device. A parameter of the current block can be determined. Based on the determined parameter of the current block, at least one or more of a number of rows of samples or a number columns of samples in a template of the current block and at least one or more of a number of rows of samples or a number columns of samples in a template of a reference picture can be determined. Motion compensation for the current block can be performed. For example, one or more local illumination compensation parameters can be derived for the current block using the template of the current block and the template of the reference picture.
