|graph|
=======================

Description
-----------

|ev74_synopsys| taking in a frame and resizing it to the desired size. Different algorightms are available for this operation.

Graph Info
----------

.. list-table:: |graph|
   :widths: 12 20
   :stub-columns: 1

   * - Graph Name
     - |graph|
   * - Graph ID
     - 8
   * - Operations Supported
     -  SIMA_RESIZE_NEAREST(0)

        SIMA_RESIZE_BILINEAR(1)

        SIMA_RESIZE_BICUBIC(2)
   * - Important Parameters to configure
     -  "input_width"   → Width of Input Image

        "input_height"  → Height of Input Image

        "output_width"  → Width of Output Image (same as input width)

        "output_height" → Height of Output Image (same as input height)

        "batch_size"    → No:of input images

        "rsz_type"     → Resize interpolation type- 0 to 2 (Refer to Operations Supported column)

   * - Available Since Yocto Build
     - B745

.. note::

   Please note that, the ``out_sz`` in above json needs to be calculated based on your output format.
   Ex. If the output format is RGB, then the ``out_sz`` will be ``output_height * output_width * 3``.
   Here, ``3`` is the number of channels
