# Introduction
This dataset is designed to aid in the detection and classification of different types of buoys in water bodies for navigation and safety purposes. The dataset includes seven classes: black, blue, green, green column, red, red column, and yellow buoys. Each class has distinct visual features that should be used for accurate annotation.

# Object Classes

## Black Buoy
### Description
A spherical buoy with a uniform black surface, often appearing matte and lacking any significant reflection.

### Instructions
Annotate the entire spherical shape of the black buoy, ensuring the bounding box includes any visible parts above the water. Do not include water reflections.

## Blue Buoy
### Description
A spherical buoy with a deep blue color, distinguishable from the water by its solid hue and shape.

### Instructions
Draw a bounding box around the blue buoy's visible sphere, ensuring clarity in separation from the surrounding water. Avoid capturing water reflections.

## Green Buoy
### Description
This buoy is spherical and possesses a bright green color, making it highly visible against the water surface.

### Instructions
Capture the entirety of the green buoy's spherical section, focusing on its visible part above water. Exclude any ripples or reflections on the water.

## Green Column Buoy
### Description
A tall, cylindrical buoy with a bright green color, standing out due to its vertical shape.

### Instructions
Outline the vertical, cylindrical portion of the buoy, ensuring the top and sides are clearly within the box. Reflections or waves on the water should not be included.

## Red Buoy
### Description
A spherical buoy with a vivid red color, easily noticeable on the water.

### Instructions
Enclose the red buoy's sphere, focusing on the portion above water level. Ignore water-related reflections.

## Red Column Buoy
### Description
A tall, red cylindrical buoy, distinctive due to its columnar shape and height.

### Instructions
Draw the boundary around the tall, red cylindrical part, covering the top edge and body. Reflections should not be annotated.

## Yellow Buoy
### Description
A bright yellow spherical buoy, distinct from other buoys due to its color and shape.

### Instructions
Create a bounding box around the visible yellow sphere of the buoy, keeping the focus on the buoy itself and not the reflections in the water.
