Picture:Outputs generated from our code– from left to right, synthetic input, defocus map output and defocused image.

Getting Started

Prerequisites

Tested environment

• Download and unzip the synthetic datasets (OneDrive | Dropbox) under ./data:

  ├── data
  │ ├── synthetic_datasets
  │ │ ├── ...
  

SYNDOF Generation

• 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 SYNDOF

• We rounded real values of defocus map into the nearest 10-th. When you read a defocus map, for example in python, read the 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.
