Image source:

```bash 
cp '/datasets/human36m/S9/Phoning-2/imageSequence/54138969/img_003201.jpg' ./54138969-img_003201.jpg
cp '/datasets/human36m/S9/Phoning-2/imageSequence/55011271/img_003201.jpg' ./55011271-img_003201.jpg

```

Convert to equal sized images:
```bash 
mogrify -resize 1000x1000! 54138969-img_003201.jpg
mogrify -resize 1000x1000! 60457274-img_003201.jpg
```

Update camera intrinsics:
```python3
import numpy as np
C = np.array([[1, 0, 0], [0, 1000/1002, 0], [0, 0, 1]])
K = np.array([])
np.dot(C, K)
```
