deepstream-app and BGR input

Accelerated Computing Intelligent Video Analytics DeepStream SDK

Hi,
I am tying to run inference with the deepstream-app , and I see that when I change the
model-color-format it doesn’t have any influence , and I don’t see this configuration is being parse.
I need to write new deepstream-app if I want to get my input in BGR?

thanks

Hi,

You should really use this configure to switch RGB/BGR format:

| Property          | Meaning               | Type/Range | Example             |
--------------------------------------------------------------------------------
|                   |                       | Integer    |                     |
| model-colorformat | Color format required | 0 = RGB    | model-colorformat=0 |
|                   | by the model.         | 1 = BGR    |                     |

May I know why you feel the configure doesn’t be passed?
Thanks.

I am running the fasterRCNN sample and I see that when I am editing:
config_infer_primary_fasterRCNN.txt
and change “model-color-format” from 0 to 1 and vise versa the result doesn’t change.
and it can’t be if the color is change from RGB to BGR
thanks

Hi,

Thanks for your update.
We will try this and update more information with you later.

Hi,

Have you deleted the TensorRT engine and recreated it?

rm VGG16_faster_rcnn_final.caffemodel_b1_fp32.engine

If the engine file exist, deepstream will launch TensorRT with the file without recompiling.
Thanks.
