SYNDOF (Synthetic Defocus Blur Image Dataset)
Picture: Outputs generated from our code– from left to right, synthetic input, defocus map output and defocused image.
This repository contains the official matlab implementation of SYNDOF generation used in the following paper:

Preparing Dataset
- Download the synthetic datasets and place it under
./data(file structure should be./data/synthetic_datasets).
Getting Started
On matlab console, type
# max_coc, input_offset, output_offset, is_random_gen, is_gpu, gpu_num
generate_blur_by_depth(29, 'data', 'out', false, true, 1)check the results under ./out, which is structured as,
.
├── ...
├── out
│ ├── blur_map/ # directory for output defocus map
│ ├── blur_map_binary/ # directory for binarized defocus map
│ ├── blur_map_norm/ # directory for normalized defocus map
│ ├── depth_decomposed/ # directory for decomposed depth
│ ├── image/ # directory for input image (with its modified name)
└── ...
Reading Defocus Map
We rounded real values of defocus map into the nearest 10th. When you read a defocus map, for example in python, read a file as follows,
image = (np.float32(cv2.imread(file_name, cv2.IMREAD_UNCHANGED))/10.)[:, :, 1]
image = image / 7. # 7 = (maxCoC - 1) / 4, where maxCoC is 29 in this case.BIBTEX

About Coupe Project
Project ‘COUPE’ aims to develop software that evaluates and improves the quality of images and videos based on big visual data. To achieve the goal, we extract sharpness, color, composition features from images and develop technologies for restoring and improving by using it. In addition,ersonalization technology through userreference analysis is under study.
