### Import Required Libraries 
```python
import os
from torchvision import transforms
import matplotlib.pyplot as plt
from filament_augmentation.loader.filament_dataloader import FilamentDataLoader
from filament_augmentation.generator.filament_dataset import FilamentDataset
from filament_augmentation.metadata.filament_metadata import FilamentMetadata
```
**To find out the number of left, right and unidentified chiralities for an interval of time.**
- The code snippet below gives the *chirality distribution*, i.e., the distribution of left, right and unidentified chiralities for an interval of time from "2015-08-01 17:36:15" to "2015-08-09 18:15:17".
- Here the petdata has big bear space observatory(BBSO) full disk solar images from (01-09) aug 2015.
- The format for start and end time should be YYYY-MM-DD HH:MM:SS.
- The ann_file or annotation file is a H-alpha based manually labelled filaments in a json file comes with petdata.
```python
__file__ = 'augmentation_process.ipynb'
bbso_json = os.path.abspath(
        os.path.join(os.path.dirname(__file__), 'petdata', 'bbso_json_data','2015_chir_data.json'))
filamentInfo = FilamentMetadata(ann_file = bbso_json, start_time = '2015-08-01 00:00:15',
                                    end_time = '2015-08-30 23:59:59')
filamentInfo.get_chirality_distribution()
```
    (22, 30, 186)
- In order to generate extra filaments for left, right or unidentified chirality by either balancing the data or getting them in required ratios to train them using an ML algorithm. A filament dataset class should be initialized which is quite similar to that of pytorch dataset class.
- The transform list should be list of torchvision [transformations](https://pytorch.org/vision/0.8/transforms.html) 
- Filament ratio is tuple variable that takes (L,R,U).
### Initializing Filament dataset 
To initialize filament dataset class follow parameters are required:
- bbso_path - BBSO full disk H-alpha solar images comes with petdata, path of the folder.
- ann_file - a H-alpha based manually labelled filaments in a json file comes with petdata.
- The format for start and end time should be YYYY-MM-DD HH:MM:SS.
```python
bbso_path = os.path.abspath(os.path.join(os.path.dirname(__file__), 'petdata', '2015'))
dataset = FilamentDataset(bbso_path = bbso_path, ann_file = bbso_json, 
                          start_time = "2015-08-01 17:36:15", end_time = "2015-08-09 17:36:15")
```

    index created!
### Setup transformations for data augmentation
The transformations function can be refered from [torchvision transforms](https://pytorch.org/vision/0.8/transforms.html)
- Here transforms variable should have list of torchvision transforms functions as shown below: 
```python
transforms1 = [
    transforms.ColorJitter(brightness=(0.25,1.25), contrast=(0.25,2.00), saturation=(0.25,2.25)),
    transforms.RandomRotation(15,expand=False,fill=110)
]
```
### Initializing data loader
- dataset = object of filament dataset class.
- batch_size = number of filaments to be generated per batch.
- filament_ratio = tuple of three values, i.e., ratios of left, right and unidentified chirality to be generated in each batch.
- n_batchs = number of batchs.
- transforms = list of torchvision transformations functions
- image_dim = image dimensions if image dimension is -1 then image will not be resize, i.e., output is original image size.
```python
data_loader = FilamentDataLoader(dataset = dataset,batch_size = 3 , filament_ratio = (1, 1, 1),n_batchs = 10, 
                                 transforms = transforms1, image_dim = 224)
```
#### How to generate 3 filament images for every batch with ratio of left as 1, right chirality as 1 and unidentified as 1 for 10 batches with original image dimension and display the images?
```python
data_loader = FilamentDataLoader(dataset = dataset,batch_size = 3 , filament_ratio = (1, 1, 1),
                                 n_batchs = 10, transforms = transforms1, image_dim = -1)
```
#### Batch -1 augmented filament images and their following labels (1=R, 0= U, -1=L)
```python
for original_imgs, transformed_imgs, labels in data_loader:
    for org_img, img, label in zip(original_imgs ,transformed_imgs, labels):
        print("Original image")
        plt.imshow(org_img, cmap='gray')
        plt.show()
        print("Transformed image")
        plt.imshow(img, cmap='gray')
        plt.show()
        print("Label",label)
    break
```

#### How to generate 10 filament images for every batch only for left and right chirality for 5 batches with image dimension of 224x224 ?
- In order to remove one type of chiraity, filament ratio, i.e., tuple(L, R, U):   
    - if L=0 that means left chirality is eliminated. Similarly, this applies to other types as well.
```python
data_loader = FilamentDataLoader(dataset = dataset,batch_size = 10 , filament_ratio = (1, 1, 0),
                                 n_batchs = 5, transforms = transforms1, image_dim = 224)

#### How to generate 10 filament images for every batch only for left and right chirality for 5 batches with image dimension of 224x224 ?
- In order to remove one type of chiraity, filament ratio, i.e., tuple(L, R, U):   
    - if L=0 that means left chirality is eliminated. Similarly, this applies to other types as well.
```python
data_loader = FilamentDataLoader(dataset = dataset,batch_size = 10 , filament_ratio = (1, 1, 0),
                                 n_batchs = 5, transforms = transforms1, image_dim = 224)
```
```python
for _, imgs, labels in data_loader:
    print("size of images ",imgs.shape)
    print("labels for each batch ",labels)

### Import Required Libraries 
```python
import os
from torchvision import transforms
import matplotlib.pyplot as plt
from filament_augmentation.loader.filament_dataloader import FilamentDataLoader
from filament_augmentation.generator.filament_dataset import FilamentDataset
from filament_augmentation.metadata.filament_metadata import FilamentMetadata
```
**To find out the number of left, right and unidentified chiralities for an interval of time.**
- The code snippet below gives the *chirality distribution*, i.e., the distribution of left, right and unidentified chiralities for an interval of time from "2015-08-01 17:36:15" to "2015-08-09 18:15:17".
- Here the petdata has big bear space observatory(BBSO) full disk solar images from (01-09) aug 2015.
- The format for start and end time should be YYYY-MM-DD HH:MM:SS.
- The ann_file or annotation file is a H-alpha based manually labelled filaments in a json file comes with petdata.
```python
__file__ = 'augmentation_process.ipynb'
bbso_json = os.path.abspath(
        os.path.join(os.path.dirname(__file__), 'petdata', 'bbso_json_data','2015_chir_data.json'))
filamentInfo = FilamentMetadata(ann_file = bbso_json, start_time = '2015-08-01 00:00:15',
                                    end_time = '2015-08-30 23:59:59')
filamentInfo.get_chirality_distribution()
```
    (22, 30, 186)
- In order to generate extra filaments for left, right or unidentified chirality by either balancing the data or getting them in required ratios to train them using an ML algorithm. A filament dataset class should be initialized which is quite similar to that of pytorch dataset class.
- The transform list should be list of torchvision [transformations](https://pytorch.org/vision/0.8/transforms.html) 
- Filament ratio is tuple variable that takes (L,R,U).
### Initializing Filament dataset 
To initialize filament dataset class follow parameters are required:
- bbso_path - BBSO full disk H-alpha solar images comes with petdata, path of the folder.
- ann_file - a H-alpha based manually labelled filaments in a json file comes with petdata.
- The format for start and end time should be YYYY-MM-DD HH:MM:SS.
```python
bbso_path = os.path.abspath(os.path.join(os.path.dirname(__file__), 'petdata', '2015'))
dataset = FilamentDataset(bbso_path = bbso_path, ann_file = bbso_json, 
                          start_time = "2015-08-01 17:36:15", end_time = "2015-08-09 17:36:15")
```
    loading annotations into memory...
    Done (t=0.07s)
    creating index...
    index created!
### Setup transformations for data augmentation
The transformations function can be refered from [torchvision transforms](https://pytorch.org/vision/0.8/transforms.html)
- Here transforms variable should have list of torchvision transforms functions as shown below: 
```python
transforms1 = [
    transforms.ColorJitter(brightness=(0.25,1.25), contrast=(0.25,2.00), saturation=(0.25,2.25)),
    transforms.RandomRotation(15,expand=False,fill=110)
]
```
### Initializing data loader
- dataset = object of filament dataset class.
- batch_size = number of filaments to be generated per batch.
- filament_ratio = tuple of three values, i.e., ratios of left, right and unidentified chirality to be generated in each batch.
- n_batchs = number of batchs.
- transforms = list of torchvision transformations functions
- image_dim = image dimensions if image dimension is -1 then image will not be resize, i.e., output is original image size.
```python
data_loader = FilamentDataLoader(dataset = dataset,batch_size = 3 , filament_ratio = (1, 1, 1),n_batchs = 10, 
                                 transforms = transforms1, image_dim = 224)
```
#### How to generate 3 filament images for every batch with ratio of left as 1, right chirality as 1 and unidentified as 1 for 10 batches with original image dimension and display the images?
```python
data_loader = FilamentDataLoader(dataset = dataset,batch_size = 3 , filament_ratio = (1, 1, 1),
                                 n_batchs = 10, transforms = transforms1, image_dim = -1)
```
#### Batch -1 augmented filament images and their following labels (1=R, 0= U, -1=L)
```python
for original_imgs, transformed_imgs, labels in data_loader:
    for org_img, img, label in zip(original_imgs ,transformed_imgs, labels):
        print("Original image")
        plt.imshow(org_img, cmap='gray')
        plt.show()
        print("Transformed image")
        plt.imshow(img, cmap='gray')
        plt.show()
        print("Label",label)
    break
```
