 ## Image transformations
-Medical image data pre-processing is challenging.  Data are often in specialized formats with rich meta information;  and the data volumes are often high-dimensional and requiring carefully designed manipulation procedures. As an important part of MONAI, powerful and flexible image transformations are provided to enable user-friednly, reproducible, optimized medical data pre-processing piepline.

 ### 1. Transforms support both Dictionary and Array format data
-1. The widely used computer vision packages (such as ``torchvision``) focus on spatially 2D array image processing. MONAI provides more domain specific transformations for both sptially 2D and 3D, and retains the flexible transformation "compose" feature.

 2.  As medical image preprocessing often requires additional fine-grained system parameters, MONAI provides transforms for input data encapsulated in a python dictionary. Users are able to specify the keys corresponding to the expected data fields and system parameters to compose complex transformations.
 
 ### 2. Medical specific transforms
-MONAI aims at providing a rich set of popular medical image specific transformamtions. These currently include, for example:
