Introduction

Image enhancement is performed using a 12-layer Residual Convolutional Neural Network that takes phone photo as an input and is trained to reproduce the corresponding image from DSLR camera.

Usage

Input

Parameter	Description	Required	Default Value
image	Image URL	Yes	---
phone	Type of DSLR phone camera	Yes	---
save_loc	DataAPI save location	No	data://.algo/deeplearning/PhotoQualityEnhancement/temp/enhanced.png

Output

Parameter	Description
enhanced_image	Enhanced image
original_image	Original image

Types of Phones

Types of phones are: iphone, sony and blackberry. Camera models are in the table below:
