## Data structures
|
||||
|
||||
Image's pixels (floating point number, a `float` for C)
|
||||
are ordonned as an array of lines of single
|
||||
componant values. Every componant is in a separate array,
|
||||
who are *glued* together by an in-memory image descriptor.
|
||||
|
||||
|
||||
## Converting to/from rgb or gray
|
||||
```
|
||||
#define MAGIC_FIMG 0x00F11F00

uint32_t magic;

|

```
|

For the current state of this struc, look at the main

## capture.sh & conf.sh
|

|

Ce [script](./capture.sh) sert à capturer une séquence d'image depuis
|
||||
une webcam.
|
||||
Deux choses à noter : il utilise un fichier de configuration
|
||||
(`source [./conf.sh](./conf.sh)) pour ajuster son fonctionnement, et il
|
||||
extrait juste une portion de l'image capturée. Une belle avancée,
|
||||
puisque cela ajoute quelques possibilités de recadrage dès
|
||||
la prise de vue.
