Download and load Houston 2013 Dataset, Trento dataset and Muufl dataset easily and swiftly. fetch_houston2013 is:
1. A fast houston2013 muufl and trento dataset fetcher that automatically downloads all data
2. A ready-to-use torch dataloader for houston2013 muufl and trento dataset
3. A toolbox for visualizing the datasets

![screenshot](screenshot.jpg)

## Quick Start
1. install this package
```bash
pip install fetch-houston2013
```
2. import and get the dataset
```python
from fetch_houston2013 import fetch_houston2013, fetch_muufl, fetch_trento, split_spmatrix
# For Houston 2013
hsi, dsm, train_label, test_label, info = fetch_houston2013()
# For Muufl
casi, lidar, truth, info = fetch_muufl()
train_label, test_label = split_spmatrix(truth, 20)
# For Trento
casi, lidar, truth, info = fetch_trento()
train_label, test_label = split_spmatrix(truth, 20)
```
3. Tips: train_label and test_label are [sparse matrix](https://docs.scipy.org/doc/scipy/reference/generated/scipy.sparse.coo_array.html), you can either convert them to np.array easily by
```python
train_label=train_label.todense()
test_label =test_label.todense()
```
or directly use them for getting the value in a very fast way:
```python
    def __getitem__(self, index):
      i = self.truth.row[index]
      j = self.truth.col[index]
      label = self.truth.data[index].item()
      x_hsi = self.hsi[:, i, j]
      x_dsm = self.dsm[:, i, j]
      return x_hsi, x_dsm, label
```

### torch
A standard ready-to-use Torch vison dataset.
```python
from fetch_houston2013 import Houston2013, Trento, Muufl
dataset = Muufl(subset='train', patch_size=11)
x_h, x_l, y, extras = dataset[0]
```
### utils
1. lbl2rgb: convert the label dataset to rgb image
2. read_roi: read exported `.txt` file of ENVI roi to sparse matrix
3. split_spmatrix: split a sparse to get the train dataset and test dataset
