==Color Pipeline==
Let's take a typical color pipeline and measure its performance on one of the entry level GPUs. Any color pipeline almost always starts with the Raw image. Before converting to RGB, you might want to do some processing on the raw which may include applying LUTs (look up tables), FPN (fixed point noise) removal and fixing white balance. Next comes demosaic/debayer followed by several further enhancement functions and a color space conversion into the desired format. This pipeline can perform in real-time on a decent entry level GPU on an 8k images and at over 100 FPS on a 2k image:
[[File:color_pipeline.png|300px|thumb|left|Color pipeline where each box represents one or more functions.]]

===Performance===
*Image size: '''8k'''
*Debayer method: DFPD
*RAW Size: 59.9 MB
*Codec: JPEG2000
*Sharpening: 7x7
*GPU: GTX 1080
*FPS: '''26 FPS'''

==Color Pipeline==
Let's take a typical color pipeline and measure its performance on one of the entry level GPUs. Any color pipeline almost always starts with the Raw image. Before converting to RGB, you might want to do some processing on the raw which may include applying LUTs (look up tables), FPN (fixed point noise) removal and fixing white balance. Next comes demosaic/debayer followed by several further enhancement functions and a color space conversion into the desired format. This pipeline can perform in real-time on a decent entry level GPU on an 8k images and at over 100 FPS on a 2k image:

Performance & Benchmark

2022-10-30T08:06:33Z

Jawad:

Measured with NVIDIA's Performance tools for Windows and Linux. Timing figure represents time of kernel/function in milliseconds (rounded) on a single GPU. The benchmarks are performed on color images with 8-bits per channel except where mentioned otherwise. The list below is a small subset of [[CUVI_Features|100+ features]] in CUVI.

==Color Pipeline==
Let's take a typical color pipeline and measure its performance on one of the entry level GPUs. Any color pipeline almost always starts with the Raw image. Before converting to RGB, you might want to do some processing on the raw which may include applying LUTs (look up tables), FPN (fixed point noise) removal and fixing white balance. Next comes demosaic/debayer followed by several further enhancement functions and a color space conversion into the desired format. This pipeline can perform in real-time on a decent entry level GPU on an 8k images and at over 100 FPS on a 2k image:
