Data Model: ResNet Phenology Classifier

Date: 2025-11-04 Feature: specs/1-phenology-classifier/spec.md

Entities

Plant Image

Description: Represents an image of a plant used for training or inference.

Fields:

• path (string): File path to the image (required)
• phase (string): Phenological phase label (required)
• width (int): Image width in pixels
• height (int): Image height in pixels

Validation Rules:

• Path must exist and be readable image file
• Phase must be one of the defined classes in CSV
• Image dimensions must be at least 224x224 for ResNet input

Phenological Phase

Description: Represents a growth stage classification for plants.

Fields:

• name (string): Phase identifier (e.g., "vegetative", "flowering") (required)
• description (string): Human-readable description of the phase
• index (int): Numerical index for model output (0-based)

Validation Rules:

• Name must be unique
• Index must be sequential starting from 0

Relationships

• Plant Image belongs to Phenological Phase (many-to-one)
• Phases are defined in the labels CSV file
