MVL Random Stimulus Datasets

About the Project

MVL Random Stimulus Datasets is a collection of datasets, each of which includes stimulus images and MATLAB scripts to generate the images. The datasets in the current collection are as follows:

• Splash-Categorical contains simple random shapes whose contour is defined by the sum of multiple sine waves of varying frequencies. The shapes are divided into 6 subsets of 25 images each, based on the similarity of the Fourier components comprising the contour. The images are labeled with a subset name (A-F) and an image number (001-025).

• Splash-Continuous contains simple random shapes, sampled from a planar dimension of the Fourier components comprising the contour. The dataset contains i) shapes sampled from two linear dimensions (orthogonal to each other), ii) shapes sampled from a circular dimension, and iii) shapes sampled from the planar dimension. Example shapes sampled from the planar dimension are shown below:

• Zebra-Categorical contains blobs with zebra-like patterns defined by white noise and a bandpass filter. The blobs are divided into 6 subsets of 25 images each, based on the similarity of the Fourier components comprising the pattern. The images are labeled with a subset name (A-F) and an image number (001-025).

• Zebra-Continuous contains blobs with zebra-like patterns, sampled from a planar dimension of the Fourier components comprising the pattern. The dataset contains i) blobs sampled from two linear dimensions (orthogonal to each other), ii) blobs sampled from a circular dimension, and iii) blobs sampled from the planar dimension. Example blobs sampled from the planar dimension are shown below:

Getting Started

Splash Categorical

Run the following scripts to generate splash shape images:

>> Step1_GenerateImages
>> Step2_BuildDataset

Or you may use the pre-generated images in the imgs-dataset/ directory.

Splash Continuous

Run the following scripts to generate splash shape images:

>> Step1_GeneratePreview
>> Step2_BuildDataset

Or you may use the pre-generated images in the imgs-dataset/ directory.

Zebra Categorical

Run the following scripts to generate zebra blob images:

>> Step1_GenerateImages
>> Step2_BuildDataset

Or you may use the pre-generated images in the imgs-dataset/ directory.

Zebra Continuous

Run the following scripts to generate zebra blob images:

>> Step1_GeneratePreview
>> Step2_BuildDataset

Or you may use the pre-generated images in the imgs-dataset/ directory.
