Benchmark environment
The measurements are taken considering the following criteria:
- Average behaviour: measurements considering typical image processing pipelines.
Instruments:
- GPU: Jtop
- CPU: RidgeRun Profiler
- RAM: RidgeRun Profiler
- Framerate: GstShark
Engine wrapper
As previously mentioned, the Spherical Video PTZ features an engine wrapper, designed for application development. This section aims to conduct performance measurements using the average value obtained after processing the input image through the 'Process' method of the Spherical Video PTZ engine wrapper. The values presented in the table below are the averages obtained after using the Process method 1000 times. This testing was conducted using the 8 cores of the MODE_30W_ALL mode on a Jetson AGX Xavier with JetPack 5.1.2.

Please consider the following points:
- Image Type: This refers to whether the input and output images use the lp/allocators/cudaimage.hpp library (images allocated in GPU memory) or the lp/image.hpp library (images allocated in CPU memory). In the results, it is evident that processing time is higher when using an Image compared to a CudaImage. This difference arises because although the engine wrapper accepts both types of images, when using an Image, the engine internally creates a copy of the CPU memory to perform operations on the GPU. This copying process consumes considerable time compared to using an image already allocated in GPU memory.
- PTZ Usage: This indicates a change in the pan, tilt, or zoom property before processing the input image. Consequently, the engine wrapper executes an additional step to calculate the output image, leading to an increase in processing time.
Gstreamer element: rrpanoramaptz
Processing time using system memory
Each of the following sections presents the pipeline used for the performance test and the resulting performance graph, depicting the processing time without PTZ transformations for different video resolutions and output sizes.

Summary
This table summarizes the average processing time for different resolutions:
| Resolution (Input – Output) | Processing Average (ms) |
|---|---|
| 2000x1000 – 500x500 | 1.08256 |

Processing time with ptz transformations
The bash script provided applies PTZ transformations to measure how they impact the processing time of the rrpanoramaptz element. The script sequentially applies a change in the pan position every 0.02 seconds, which introduces additional computational work for the processing element. This is reflected in the measured processing times, providing a realistic understanding of the element's performance under PTZ operations.
