# cv-aid
CV Aid is a set of helpers of computer vision tasks.
## Installation
`pip install cv-aid`
### From source
```
git clone https://github.com/khalidelboray/cv-aid
cd cv-aid
poetry install
poetry run python setup.py install
```
## Tests
`poetry run test`
all tests are in `tests/` directory.
## Examples
- Basic Frame Functions
```python
from cv_aid import Frame
frame = Frame.load('/path/to/image.jpg')
# or
import cv2
frame = Frame(cv2.imread('/path/to/image.jpg'))
# Grayscale image
gray = frame.gray()
# Resize image
small = frame.resize(width=100, height=100)
# Crop image
cropped = frame.crop(x=100, y=100, width=100, height=100)
# All methods return a new Frame object, so you can chain them
new_frame = frame.resize(width=100, height=100).crop(x=100, y=100, width=100, height=100)
# Save image
frame.save('/path/to/image.jpg')
```
- Basic Video Functions
```python
from cv_aid import VideoStream, Frame
import cv2
import numpy as np
def on_frame(frame: Frame) -> Frame:
"""
A function that is called when a frame is read from the video stream.
:param frame: The frame that was read.
:return: The frame that was read.
"""
orig = frame
canny = frame.gray().canny(50, 100)
line_image = Frame(np.copy(orig.frame) * 0)
lines = cv2.HoughLinesP(
canny.frame, 1, np.pi / 180, 50, np.array([]), minLineLength=10, maxLineGap=5
)
if lines is not None:
for line in lines:
line = line[0]
line_image = line_image.line(
(line[0], line[1]), (line[2], line[3]), (0, 255, 0), 3
)
lines_edges = cv2.addWeighted(orig.frame, 0.8, line_image.frame, 1, 1)
return Frame(lines_edges)
stream = VideoStream(src=0, on_frame=on_frame).start()
stream.start_window()
```
*Output Demo:*
- Haar Cascade Functions
```python
from cv_aid import VideoStream, Frame
def on_frame(frame: Frame) -> Frame:
"""
A function that is called when a frame is read from the video stream.
:param frame: The frame that was read.
:return: The frame that was read.
"""
boxes = frame.haarcascades.detect_faces(frame.frame, scaleFactor=1.1, minNeighbors=5, minSize=(30, 30))
frame = frame.boxes(boxes, color=(0, 255, 0))
return frame
if __name__ == "__main__":
stream = VideoStream(src=0, on_frame=on_frame).start()
stream.start_window()
```
*Output Demo:*
- Tourch Hub (Yolov5)
```python
from cv_aid import VideoStream, Frame
import torch
model = torch.hub.load('ultralytics/yolov5', 'yolov5s')
def on_frame(frame: Frame) -> Frame:
"""
A function that is called when a frame is read from the video stream.
:param frame: The frame that was read.
:return: The frame that was read.
"""
results = model(frame.frame)
results.display(render=True)
frame = Frame(results.imgs[0])
return frame
if __name__ == "__main__":
stream = VideoStream(src=0, on_frame=on_frame).start()
stream.start_window()
```
- Dlib (`Download model`)
```python
from cv_aid._dlib import Dlib
saved_model = Dlib.download_landmark_detector(path='/dir/to/download/model/at/')
dlib = Dlib(landmark_predictor_path=saved_model)
face_recognetion_model = Dlib.download_face_recognition_model_v1(path='/dir/to/download/model/at/')
```
- Dlib (Face landmark)
