Members

Member	Description
kernel_size	Size of the convolution kernel. The width and height of kernel_size can only be set to 1, 3, or 5. For details, see hi_size.
morph_shapes	Filtering convolution shape. For details, see hi_morph_shapes.
anchor	Convolution kernel anchor, which needs to be set to (–1, –1). This field is reserved. For details, see hi_point.
iterations	Number of convolution iterations. The value range is [1, 100]. For mean filtering processing, the value can only be set to 1. For corrosion or expansion processing, the value may be any one within the range of [1, 100].
border_type	Border making type. Only the HI_BORDER_CONSTANT and HI_BORDER_REPLICATE modes are supported. For details, see hi_vpc_bord_type.
scalar_value	Border making value. For details, see hi_vpc_scalar.
