+ # Dataset Card for LenslessMic Version of N(0,1) Random Dataset
10
+
11
+ ## Dataset Summary
12
+ A LenslessMic version of the N(0,1) random images dataset from the
13
+ ["LenslessMic: Audio Encryption and Authentication via Lensless Computational Imaging"](https://arxiv.org/abs/2509.16418) paper.
14
+ The dataset can be used to train a codec-agnostic reconstruction algorithm.
15
+
16
+ | Partition | # Audio | # Frames |
17
+ |--------------|---------|----------|
18
+ | train | 200 | 30000 |
19
+
20
+ **Note**: We split dataset into 200 files, however, there are no actual audio files. Only frames are used.
21
+
22
+ To download the dataset and work with it, use our [official repository](https://github.com/Blinorot/LenslessMic).
23
+
24
+ Dataset is collected using [DigiCam](https://arxiv.org/abs/2502.01102). Setup configuration:
25
+
26
+ | Parameter | Value |
27
+ |-------------------------------------------|--------------------|
28
+ | Screen Size | [1920, 1200] |
29
+ | Screen Pixel-Pitch | 0.27 mm |
30
+ | Screen-To-Mask Distance | 30e-2 m |
31
+ | Sensor Size | [4056, 3040] |
32
+ | Sensor Size Downsample Coefficient | 8 |
33
+ | Sensor Pixel-Pitch | 1.55 Γ— 10⁻⁢ m |
34
+ | Mask-To-Sensor Distance | β‰ˆ 4e-3 m |
35
+ | Image size on the Screen (256 case) | 928 Γ— 928 |
36
+ | Image size on the Screen (288 case) | 1044 Γ— 1044 |
37
+ | Vertical Shift on the Screen (256 case) | -23 |
38
+ | Vertical Shift on the Screen (288 case) | -20 |
39
+ | Number of masks | 100 |
40
+ | Mask Aperture Shape (for 1/3 channels) | [18, 24] |
41
+ | Mask Center | [55, 77] |
42
+
43
+ For other configuration, please refer to the codebase above.
44
+
45
+ ## Dataset Structure
46
+ Dataset is structured in the following format:
47
+
48
+ ```
49
+ .
50
+ └── partition_name
51
+ └── image_size # 16x16 or 32x32
52
+ β”œβ”€β”€ lensed # lensed version of the video representation
53
+ | └── filename_i.mkv # normalized video representation of i-th audio file using this codec
54
+ └── lensless_measurement # lensless version captured using LenslessMic
55
+ β”œβ”€β”€ filename_i.mkv # lensless video of the i-th audio file
56
+ β”œβ”€β”€ filename_i.txt # label 'j' of the mask from the masks dir used for this video
57
+ └── masks # masks for the lensless camera
58
+ └── mask_j.npy # mask pattern
59
+ ```
60
+
61
+ Apart from other LenslessMic datasets, this one does not use any audio codecs. These are just random images from N(0,1).
62
+ The dataset can be used to train a codec-agnostic reconstruction algorithm. No min/max vals are used (set to 0 and 1).
63
+
64
+ Some codecs have different types of lensless measurements:
65
+
66
+ 1. `lensless_measurement`: standard version. Resizes images in a screen in a such a way that they have size 256x256 on the sensor.
67
+
68
+ Region of interest for the reconstruction for this dataset is:
69
+
70
+ | Sensor Image Size | Top Left Corner | Height | Width |
71
+ | ----------------- | --------------- | ------ | ----- |
72
+ | 256 x 256 | [65, 118] | 256 | 256 |
