BCCD Dataset is a small-scale dataset for blood cells detection.

Thanks the original data and annotations from cosmicad and akshaylamba. The original dataset is re-organized into VOC format. BCCD Dataset is under MIT licence.

Data preparation is important to use machine learning. In this project, the Faster R-CNN algorithm from keras-frcnn for Object Detection is used. From this dataset, nicolaschen1 developed two Python scripts to make preparation data (CSV file and images) for recognition of abnormalities in blood cells on medical images.

export.py: it creates the file "test.csv" with all data needed: filename, class_name, x1,y1,x2,y2. plot.py: it plots the boxes for each image and save it in a new directory.

Image Type : jpeg(JPEG) Width x Height : 640 x 480

To use this dataset:

import tensorflow_datasets as tfds

ds = tfds.load('bccd', split='train')
for ex in ds.take(4):
 print(ex)

On February 8, 2021, Deception Island Chinstrap penguin colonies were photographed during the PiMetAn Project XXXIV Spanish Antarctic campaign using unmanned aerial vehicles (UAV) at a height of 30m. From the obtained imagery, a training dataset for penguin detection from aerial perspective was generated.

The penguin species is the Chinstrap penguin (Pygoscelis antarcticus).

The dataset consists of three folders: "train", containing 531 images, intended for model training; "valid", containing 50 images, intended for model validation; and "test", containing 25 images, intended for model testing. In each of the three folders, an additional .csv file is located, containing labels (x,y positions and class names for every penguin in the images), annotated in Tensorflow Object Detection format.

There is only one annotation class: Penguin.

All 606 images are 224x224 px in size, and 96 dpi.

The following augmentation was applied to create 3 versions of each source image: * Random shear of between -18° to +18° horizontally and -11° to +11° vertically

This dataset was annotated and exported via www.roboflow.com

The model Faster R-CNN64 with ResNet-101 backbone was used to perform object detection tasks. Training and evaluation tasks were performed using the TensorFlow 2.0 machine learning platform by Google.

This Project consists of two datasets, both of aerial images and videos of dolphins, being taken by drones. The data was captured from few places (Italy and Israel coast lines).

The aim of the project is to examine automated dolphins detection and tracking from aerial surveys.

The project description, details and results are presented in the paper (link to the paper).

Each dataset was organized and set for a different phase of the project. Each dataset is located in a different zip file:

1. Detection - Detection.zip

2. Tracking - Tracking.zip

Further information about the datasets' content and annotation format is below.

• In aim to watch each file content, use the preview option, in addition a description appears later on this section.

Detection Dataset

This dataset contains 1125 aerial images, while an image can contain several dolphins.

The detection phase of the project is done using RetinaNet, supervised deep learning based algorithm, with the implementation of Keras RetinaNet. Therefore, the data was divided into three parts - Train, Validation and Test. The relations is 70%, 15%, 15% respectively.

The annotation format follows the requested format of that implementation (Keras RetinaNet). Each object, which is a dolphin, is annotated as a bounding box coordinates and a class. For this project, the dolphins were not distinguished into species, therefore, a dolphin object is annotated as a bounding box, and classified as a 'Dolphin'. Detection zip file includes:

A folder for each - Train, Validation and Test subsets, which includes the images

An annotations CSV file for each subset

A class mapping csv file (one for all the subsets).

*The annotation format is detailed in Annotation section.

Tracking

This dataset contains 5 short videos (10-30 seconds), which were trimmed from a longer aerial videos, captured from a drone.

The tracking phase of the project is done using two metrics:

VIAME application, using the tracking feature

Re3: Real-Time Recurrent Regression Networks for Visual Tracking of Generic Objects, by Daniel Gordon. For this project, the author's Tensorflow implementation is being used

Both metrics demand the videos' frames sequence as an input. Therefore, the videos' frames were extracted. The first frame was annotated manually for initialization, and the algorithms track accordingly. Same as the Detection dataset, each frame can includes several objects (dolphins).

For annotation consistency, the videos' frames sequences were annotated similar to the Detection Dataset above, (details can be found in Annotation section). Each video's frames annotations separately. Therefore, Tracking zip file contains a folder for each video (5 folders in total), named after the video's file name.

Each video folder contains:

Frames sequence directory, which includes the extracted frames of the video

An annotations CSV file

A class mapping CSV file

The original video in MP4 format

The examined videos description and details are displayed in 'Videos Description.xlsx' file. Use the preview option for displaying its content.

Annotations format

Both datasets have similar annotation format which is described below. The data annotation format, of both datasets, follows the requested format of Keras RetinaNet Implementation, which was used for training in the Dolphins Detection phase of the project.

Each object (dolphin) is annotated by a bounding box left-top and right-bottom coordinates and a class. Each image or frame can includes several objects. All data was annotated using Labelbox application.

For each subset (Train, Validation and Test of Detection dataset, and each video of Tracking Dataset) there are two corresponded CSV files:

Annotations CSV file

Class mapping CSV file

Each line in the Annotations CSV file contains an annotation (bounding box) in an image or frame. The format of each line of the CSV annotation is:

path/to/image.jpg - a path to the image/frame

x1, y1 - image coordinates of the left upper corner of the bounding box

x2, y2 - image coordinates of the right bottom corner of the bounding box

class_name - class name of the annotated object

path/to/image.jpg,x1,y1,x2,y2,class_name

An example from train_set.csv:

.\train_set\1146_20170730101_ce1_sc_GOPR3047 103.jpg,506,644,599,681,Dolphin .\train_set\1146_20170730101_ce1_sc_GOPR3047 103.jpg,394,754,466,826,Dolphin .\train_set\1147_20170730101_ce1_sc_GOPR3047 104.jpg,613,699,682,781,Dolphin .\train_set\1147_20170730101_ce1_sc_GOPR3047 104.jpg,528,354,586,443,Dolphin .\train_set\1147_20170730101_ce1_sc_GOPR3047 104.jpg,633,250,723,307,Dolphin

This defines a dataset with 2 images:

1146_20170730101_ce1_sc_GOPR3047 103.jpg which contains 2 objects classified as 'Dolphin'

1146_20170730101_ce1_sc_GOPR3047 104.jpg which contains 3 objects classified as 'Dolphin'

Each line in the Class Mapping CSV file contains a mapping:

class_name,id

An example:

Dolphin,0
