Traitly is an open-source Python tool for automated, high-throughput fruit phenotyping from digital images. Using computer vision methods, it quantifies morphological, symmetry, and color traits across both internal structures and the external appearance of the fruit.

It supports both single-image analysis and batch processing workflows, making it easy to handle large image datasets with just a few lines of code, which is especially useful in plant breeding programs and research.

What can Traitly do?

Traitly processes fruit images to measure:

• Fruit morphology: Area, perimeter, circularity, dimensions, and aspect ratio
• Locule anatomy: Locule number, size distribution, and spatial arrangement
• Pericarp structure: Thickness, uniformity (CV), and surface irregularity (lobedness)
• Color phenotypes: Multi-channel analysis (RGB, HSV, Lab) across different fruit regions

Usage

Traitly can be used from Python, the command line (CLI), or as a web application (Shiny App). For more details:
