Intruder Detection - Dataset Ninja

Introduction #

Tarun Bisht

The author of the Intruder Detection dataset assembled this data for a research project concerning monkey theft detection. To enhance its versatility and applicability, the dataset incorporates three additional categories beyond monkeys, comprising people, dogs, and cats.

Summary #

Intruder Detection is a dataset for an object detection task. Possible applications of the dataset could be in the security industry.

The dataset consists of 14478 images with 28843 labeled objects belonging to 4 different classes including dog, cat, person, and other: monkey.

Images in the Intruder Detection dataset have bounding box annotations. All images are labeled (i.e. with annotations). There are 2 splits in the dataset: train (11091 images) and test (3387 images). The dataset was released in 2021.

Here are the visualized examples for the classes:

Explore #

Intruder Detection dataset has 14478 images. Click on one of the examples below or open "Explore" tool anytime you need to view dataset images with annotations. This tool has extended visualization capabilities like zoom, translation, objects table, custom filters and more. Hover the mouse over the images to hide or show annotations.

Class balance #

There are 4 annotation classes in the dataset. Find the general statistics and balances for every class in the table below. Click any row to preview images that have labels of the selected class. Sort by column to find the most rare or prevalent classes.

Rows 1-4 of 4

Class ㅤ	Images ㅤ	Objects ㅤ	Count on image average	Area on image average
dog➔ rectangle	4000	5509	1.38	45.17%
cat➔ rectangle	3962	4644	1.17	54.77%
person➔ rectangle	3951	15121	3.83	35.57%
monkey➔ rectangle	2565	3569	1.39	43.76%

Co-occurrence matrix #

Co-occurrence matrix is an extremely valuable tool that shows you the images for every pair of classes: how many images have objects of both classes at the same time. If you click any cell, you will see those images. We added the tooltip with an explanation for every cell for your convenience, just hover the mouse over a cell to preview the description.

Images #

Explore every single image in the dataset with respect to the number of annotations of each class it has. Click a row to preview selected image. Sort by any column to find anomalies and edge cases. Use horizontal scroll if the table has many columns for a large number of classes in the dataset.

Class sizes #

The table below gives various size properties of objects for every class. Click a row to see the image with annotations of the selected class. Sort columns to find classes with the smallest or largest objects or understand the size differences between classes.

Rows 1-4 of 4

Class	Object count	Avg area	Max area	Min area	Min height	Min height	Max height	Max height	Avg height	Avg height	Min width	Min width	Max width	Max width

Spatial Heatmap #

The heatmaps below give the spatial distributions of all objects for every class. These visualizations provide insights into the most probable and rare object locations on the image. It helps analyze objects' placements in a dataset.

Objects #

Table contains all 28843 objects. Click a row to preview an image with annotations, and use search or pagination to navigate. Sort columns to find outliers in the dataset.
