| * 3x3 convolution with stride_x = 1/2, stride_y = 1/2 |
| * 5x5 convolution with stride_x = 1/2, stride_y = 1/2 |
| * |
| * @param[in] input The input tensor to convolve. 3 lower dimensions represent a single input [width, height, IFM], |
| * while every optional dimension from 4 and above represent a batch of inputs. Data types supported: QASYMM8/QS8/QS16/F16/F32. |
| * @param[in] weights Weights tensor. Weights are 4D tensor with dimensions [kernel_x, kernel_y, IFM, OFM]. |
| * The 3rd dimension must be the same as the input's volume 3rd dimension. |
| * Data type supported:Same as @p input. |
| * @param[in] biases Biases tensor. Biases are 1D tensor with dimension [OFM]. |
| * Data type supported: Should match @p input data type, except for input of QASYMM8 type where biases should be of S32 type |
| * @param[out] output Output tensor. |
| * The 3rd dimensions must be equal to the 4th dimension of the @p kernels tensor. Data types supported: Same as @p input. |
| * @param[in] conv_info Contains padding and stride information described in @ref PadStrideInfo. |
