+# IPFML
+
+Image Processing For Machine Learning package.
+
+## Modules
+
+This project contains modules.
+
+### **img_processing** : *PIL image processing part*
+    - fig2data(fig): *Convert a Matplotlib figure to a 3D numpy array with RGB channels and return it*
+    - fig2img(fig): *Convert a Matplotlib figure to a PIL Image in RGB format and return it*
+
+### **metrics** : *Metrics computation of PIL image*
+    - get_SVD(image): *Transforms PIL Image into SVD*
+    - get_SVD_s(image): *Transforms PIL Image into SVD and returns only 's' part*
+    - get_SVD_U(image): *Transforms PIL Image into SVD and returns only 'U' part*
+    - get_SVD_V(image): *Transforms PIL Image into SVD and returns only 'V' part*
+
+### **ts_model_helper** : *contains helpful function to save or display model information and performance of tensorflow model*
+    - save(history, filename): *Function which saves data from neural network model*
+    - show(history, filename): *Function which shows data from neural network model*
+
+All these modules will be enhanced during development of the project
+
+## How to contribute
+
+This git project uses [git-flow](https://danielkummer.github.io/git-flow-cheatsheet/) implementation. You are free to contribute to it.
