This is a background removing tool powered by InSPyReNet (ACCV 2022). You can easily remove background from the image or video or bunch of other stuffs when you can make the background transparent!

--jit
option, also known as TorchScript option is widely used recently for disabling dynamic resizing for stable output. Since it wasn't mean to be used in this way, I added--resize
option. For those who used--jit
option because of the stability, you don't have to specify anymore. You may also access to this option in python API and GUI mode.- Default option is
--resize static
which provides less detailed prediction but more stable --resize dynamic
option was the previous default option which was disabled by--jit
option previously. This will provide more detailed prediction but less stable than--resize static
option.
- Default option is
- Our package is currently not working properly on small images without
--fast
argument. Sorry for the inconvenience and we'll fix this issue with better algorithm coming out shortly. - [2023.09.22] For the issue with small images without
--fast
argument, please download This Checkpoint. After some user feedback (create issue or contact me), I'll decide to substitute the current checkpoint to the newer one or train again with different approach. - [2023.09.25] The above checkpoint is now available with
--mode base-nightly
argument.--fast
argument is deprecated. Use--mode [MODE]
instead.--mode
argument supportsbase
,fast
andbase-nightly
. Note thatbase-nightly
can be changed without any notice. - [2023.10.19] Webcam support is not stable currently. We remove the dependency for the latest release. Install with extra dependency option
pip install transparent-background[webcam]
if you want to use webcam input. - [2024.02.14] I added a github sponsor badge. Please help maintaining this project if you think this package is useful!
- [2024.08.22] ComfyUI-Inspyrenet-Rembg is implemented by john-mnz. Thank you for sharing great work!

Note: If you have any problem with pyvirtualcam
, please visit their github repository or pypi homepage. Due to the backend workflow for Windows and macOS, we only support Linux for webcam input.
We basically follow the virtual camera settings from pyvirtualcam
. If you do not choose to install virtual camera, it will visualize real-time output with cv2.imshow
.

transparent-background
now supports external configuration rather than hard coded assets (e.g., checkpoint download url).
- The config file will be added in your home directory
~/.transparent-background/config.yaml
by default. The directory location can be customized by setting the desired file path under the environment variableTRANSPARENT_BACKGROUND_FILE_PATH
. (Contributed by kwokster10) - You may change the
url
argument to your Google Drive download link. (Please note that only Google Drive is supported.) - You may change the
md5
argument to your file's md5 checksum. Or, setmd5
toNULL
to skip verification. - You may add
http_proxy
argument to specify the proxy address as you need. If your internet connection is behind a HTTP proxy (e.g.http://192.168.1.80:8080
), you can set this argument. (Contributed by bombless)

: Specify your data in this argument.- Single image -
image.png
- Folder containing images -
path/to/img/folder
- Single video -
video.mp4
- Folder containing videos -
path/to/vid/folder
- Integer for webcam address -
0
(e.g., if your webcam is at/dev/video0
.)
- Single image -
--dest [DEST]
(optional): Specify your destination folder. Default location is current directory.--threshold [THRESHOLD]
(optional): Designate threhsold value from0.0
to1.0
for hard prediction. Do not use if you want soft prediction.--type [TYPE]
(optional): Choose betweenrgba
,map
green
,blur
,overlay
, and another image file. Default isrgba
.rgba
will generate RGBA output regarding saliency score as an alpha map. Note that this will not work for video and webcam input.map
will output saliency map only.green
will change the background with green screen.white
will change the background with white color. -> [2023.05.24] Contributed by carpedm20'[255, 0, 0]'
will change the background with color code [255, 0, 0]. Please use with single quotes. -> [2023.05.24] Contributed by carpedm20blur
will blur the background.overlay
will cover the salient object with translucent green color, and highlight the edges.- Another image file (e.g.,
samples/backgroud.png
) will be used as a background, and the object will be overlapped on it.
--ckpt [CKPT]
(optional): Use other checkpoint file. Default is trained with composite dataset and will be automatically downloaded if not available. Please refer to Model Zoo from InSPyReNet for available pre-trained checkpoints.--mode [MODE]
(optional): Choose frombase
,base-nightly
andfast
mode. Usebase-nightly
for nightly release checkpoint.- โญ
--resize [RESIZE]
(optional): Choose betweenstatic
anddynamic
. Dynamic will produce better results in terms of sharper edges but maybe unstable. Default isstatic
- โญ
--format [FORMAT]
(optional): Specify output format. If not specified, the output format will be identical to the input format. - โญ
--reverse
(optional): Reversing result. In other words, foreground will be removed instead of background. This will make our package's nametransparent-foreground
! ๐ --jit
(optional): Torchscript mode. If specified, it will trace model with pytorch built-in torchscript JIT compiler. May cause delay in initialization, but reduces inference time and gpu memory usage.
- Usage Example
import cv2
import numpy as np
from PIL import Image
from transparent_background import Remover
# Load model
remover = Remover() # default setting
remover = Remover(mode='fast', jit=True, device='cuda:0', ckpt='~/latest.pth') # custom setting
remover = Remover(mode='base-nightly') # nightly release checkpoint
remover = Remover(resize='dynamic') # use dynamic resizing instead of static resizing
# Usage for image
img = Image.open('samples/aeroplane.jpg').convert('RGB') # read image
out = remover.process(img) # default setting - transparent background
out = remover.process(img, type='rgba') # same as above
out = remover.process(img, type='map') # object map only
out = remover.process(img, type='green') # image matting - green screen
out = remover.process(img, type='white') # change backround with white color
out = remover.process(img, type=[255, 0, 0]) # change background with color code [255, 0, 0]
out = remover.process(img, type='blur') # blur background
out = remover.process(img, type='overlay') # overlay object map onto the image
out = remover.process(img, type='samples/background.jpg') # use another image as a background
out = remover.process(img, threshold=0.5) # use threhold parameter for hard prediction.
out = remover.process(img, reverse=True) # reverse output. background -> foreground
out.save('output.png') # save result
out.save('output.jpg') # save as jpg
# Usage for video
cap = cv2.VideoCapture('samples/b5.mp4') # video reader for input
fps = cap.get(cv2.CAP_PROP_FPS)
writer = None
while cap.isOpened():
ret, frame = cap.read() # read video
if ret is False:
break
frame = cv2.cvtColor(frame, cv2.COLOR_BGR2RGB)
img = Image.fromarray(frame).convert('RGB')
if writer is None:
writer = cv2.VideoWriter('output.mp4', cv2.VideoWriter_fourcc(*'mp4v'), fps, img.size) # video writer for output
out = remover.process(img, type='map') # same as image, except for 'rgba' which is not for video.
writer.write(cv2.cvtColor(np.array(out), cv2.COLOR_BGR2RGB))
cap.release()
writer.release()
