# pyshine

A collection of simply yet high level utilities for Python.

## Installation

### Installing dependencies

Provided the below python packages are installed, pyshine is completely pip installable.



### Installing pyshine

`pip install pyshine`

To upgrade to the newest version
`pip install --upgrade pyshine`


### pyshine.putBText()

putBText(): Put Background Box with Text

```
Inputs:
img: cv2 image img
text_offset_x, text_offset_x: X,Y location of text start
vspace, hspace: Vertical and Horizontal space between text and box boundries
font_scale: Font size
background_RGB: Background R,G,B color
text_RGB: Text R,G,B color
font: Font Style e.g. cv2.FONT_HERSHEY_DUPLEX,cv2.FONT_HERSHEY_SIMPLEX,cv2.FONT_HERSHEY_PLAIN,cv2.FONT_HERSHEY_COMPLEX
      cv2.FONT_HERSHEY_TRIPLEX, etc
thickness: Thickness of the text font
alpha: Opacity 0~1 of the box around text
gamma: 0 by default

Output:
img: CV2 image with text and background
```

### usage



```python3
import pyshine as ps
import cv2
image = cv2.imread('lena.jpg')
text  =  'HELLO WORLD!'
image =  ps.putBText(image,text,text_offset_x=20,text_offset_y=20,vspace=10,hspace=10, font_scale=1.0,background_RGB=(228,225,222),text_RGB=(1,1,1))
cv2.imshow('Output', image)
cv2.waitKey(0)
```



### pyshine.audioCapture()

audioCapture(): Send or Get the Audio from pc Microphone

```
Inputs:
mode: 'send' to send the audio chunk data or 'get' to receive the audio data

Output:
audio: Audio data, which can be accessed using audio.get() or send using audio.put()
```

### usage

```python3
import pyshine as ps
mode =  'send'
audio=audioCapture(mode)

```

### pyshine.showPlot()

showPlot(): Plots the live data 

```
Inputs:
audio: audio data obtained 
name: 'Tile of the plot'
length defult 8 times 1024
xmin: default 0 along the x axis
ymin: default -0.5 along the x axis
xmax: default 8*1024 along the y axis
ymax: default 0.5 along the y axis
color: Color of the plot (0,1,0.29)


Output:
show the plot()
```

### usage

```python3
import pyshine as ps
mode =  'send'
audio,context=ps.audioCapture(mode=mode)
name =  'pyshine.com'
ps.showPlot(context,name=name)
while True:
	frame = audio.get()



```

### pyshine.RPSNET

A CNN model for the Keras library, incorporating Rock, Paper, Scissor learnining Network.

```python
import pyshine as ps
from keras.optimizers import Adam

# WIDTH : width of image about 80 pixels
# HEIGHT : height of image about 80 pixels
# DEPTH : dimensions of image such as 3
# NUM_CLASSES : number of classes to classify as output
model =ps.RPSNET.build(width=WIDTH, height=HEIGHT, depth=DEPTH, classes=NUM_CLASSES)
```

```python
INIT_LR = 1e-3
EPOCHS = 1000
OPT = Adam(lr=INIT_LR, decay=INIT_LR / EPOCHS)
model.compile(
		optimizer=OPT,
		loss='categorical_crossentropy',
		metrics=['accuracy']
		)
# data: numpy image array containing data samples
# labels: corresponding labels per data
model.fit(np.array(data), np.array(labels),epochs=EPOCHS)
model.save("RPS-model.h5")
pred = model.predict(np.array([image]))

```

### pyshine.Streamer

Low latency video streamer for webcams and raspberry pi camera.
