# Control Point Detector Parameters

This site will give you an overview about the different control point detectors and their main options to use with hugin. This settings can be changed in preferences dialog. A detailed description of the individual settings can be found here

# Cpfind

- For outdoor projects, single and multi-row panorama

Detector Type | All images at once
--- | ---
Detector | One-step detector
Program | `cpfind`
Arguments | `--multirow --celeste -o %o %s`

- For indoor projects, single and multi-row panorama

Detector Type | All images at once
--- | ---
Detector | One-step detector
Program | `cpfind`
Arguments | `--multirow -o %o %s`

- For very big outdoor projects, single and multi-row panorama, with caching to disc

Detector Type | Multi-row panoramas
--- | ---
Detector | One-step detector
Program | `cpfind`
Arguments | `--cache --celeste -o %o %s`
Cleanup arguments | `--clean %s`

Hints:

- MacOSX: Both in the bundle version as in the cmake version you need to add cpfind without browsing for it and without adding a pathname, just cpfind.

# Panomatic

- For general projects

Detector Type | All images at once or Multi-row panorama
--- | ---
Detector | One-step detector
Program | `panomatic`
Arguments | `-o %o %i`

- For single-row projects

Detector Type | All images at once
--- | ---
Detector | One-step detector
Program | `panomatic`
Arguments | `--linearmatch -o %o %i`

# Autopano-sift-C

- For general projects

Detector Type | All images at once
--- | ---
Detector | One-step detector
Program | `autopano-sift-c`
Arguments | `--maxmatches %p --projection %f,%v %o %i` in version in Mercurial the parameter --projection is broken, use instead `--maxmatches %p %o %i` or `--maxmatches %p %o %s` (the latter works also for bigger projects)

- For multi-row projects

Detector Type | Multi-row panorama
--- | ---
Detector | Two-step detector
Feature descriptor | `generatekeys`
Arguments | `%i %k 800`
Feature matcher | `autopano`
Arguments | `--maxmatches %p %o %k`

# Autopano by Alexandre Jenny

Detector Type | Autopano (by A. Jenny)
--- | ---
Detector | One-step detector
Program | `autopano`
Arguments | `/allinone /path:%d /keys:%p /project:oto /name:%o /size:1024 /f %i`

Hints:

- Autopano runs only on Windows and Linux. There is no MacOS version.
- Don't mix autopano by A. Jenny with autopano from autopano-sift-C package.

# Align_image_stack

- As standalone detector for HDR images

Detector Type | All images at once
--- | ---
Detector | One-step detector
Program | `align_image_stack`
Arguments | `-f %v -v -p %o %i` or `-f %v -v -e -p %o %i` for full-frame fisheye images

Align_image_stack can also be used in conjugation with the above mentioned detector as special case for stacks. For this use case set Detector Type to Panorama with stacks or Multi-row panorama with stacks and set the options for align_image_stack on the tab Detector for stacks

Hints:

- MacOSX: Both in the bundle version as in the cmake version you need to add align_image_stack without browsing for it and without adding a pathname, just align-image_stack.
