ObjectFinder is a MATLAB app that allows you to recognize a large number of small structures within a three-dimensional image volume.

This app is developed for neuroscience research, with the purpose of detecting fluorescently-labeled synapses in neuronal image stacks acquired using confocal or super-resolution microscopes.

Key features:
- Multi-threaded 3D object connectivity search within large image volumes
- Trainable deep learning classifier for automatic validation of objects
- Visual interaction with objects using the builtin volume inspector
- 3D inspection and interaction of detected objects using Bitplane Imaris
- Automated colocalization analysis
- Automated nearest neighbor analysis
- Integrated plots of detected object's statistics
- Export analysis results to Microsoft Excel®
- Batch processing of multiple images with custom start time
