# FloatImg4PythonBinding
|
||||
|
||||
Un fork de la galactique bibliothèque FloatImg de tTh, réaménagé pour permettre une utilisation depuis Python avec l'embryonnaire binding https://git.tetalab.org/Mutah/python-FloatImg/ (seulement sur la branche develop pour le moment)
|
||||
|
||||
Pas de révolution mais :
|
||||
|
||||
- production d'une bibliothèque partagée
|
||||
- arborescence remanié : les meubles ont changés de place : les sources sont dans `src`, les expérimentations dans `extra` et les binaires sont produits dans `build`
|
||||
- build system : un Makefile racine avec des cibles générales : `all` pour tout builder, `lib` pour la bibliothèque de base, `funcs`
|
||||

## Dépendances
|

|
||||
@ -42,41 +41,22 @@ Bien entendu, avant tout, il faut installer quelques outils et
|
||||
dépendances. Je vais tenter de les lister dans le plus grand
|
||||
désordre (à la sauce Debian) :
|
||||
|
||||
```
|
||||
apt install libtiff-dev
|
||||
apt install libpnglite-dev
|
||||
apt install liblo-dev
|
||||
apt install libv4l2-dev
|
||||
apt install libcfitsio-dev
|
||||
apt install libnetpbm-dev
|
||||
apt install libncurses-dev
|
||||
```
|
||||
Bon, OK, je suis en train de changer de machine, et ça serait vraiment
|
||||
cool d'avoir juste une ligne à c'n'p, donc voila :
|
||||
|
||||
```
|
||||
apt install libtiff-dev libpnglite-dev liblo-dev libv4l2-dev \
|
||||
libcfitsio-dev libnetpbm-dev libncurses-dev
|
||||
```
|
||||
Il est probable que j'en oublie.
|
||||
Et ya Debian qui change des trucs, alors, ça marche plus, du
|
||||
genre que c'est la deuxième fois que ça m'arrive.
|
||||
|
||||
```
|
||||
E: Unable to locate package libv4l2-dev

```bash

sudo apt install libtiff-dev libpnglite-dev liblo-dev libv4l2-dev libcfitsio-dev libnetpbm-dev
|
||||
```
|
||||
|
||||

```bash
|
||||
sudo apt install libtiff-dev libpnglite-dev liblo-dev libv4l-dev libcfitsio-dev libnetpbm10-dev libncurses5-dev
|
||||
```
|
||||
|
||||
Ensuite, j'ai dans l'idée de construire
|
||||
um meta-packet à la sauce Debian pour installer facilement tout ce
|
||||
qui sert à faire fonctionner ce kluge. Ensuite, j'irais voir du
|
||||
coté de pkg-config.

||||
Certains outils externes sont aussi utiles :
|
||||
|
||||
- gnuplot, pour analyser des données,
|
||||
- ImageMagick, parce que Brunus aime ça,
|
||||
- LaTeX, pour la (trop maigre) documentation.

# Expérimentations ÀLC
|
||||
|
||||
Attention, tout ce qui se trouve dans ce répertoire ne sont que des
|
||||
essais. Certains aboutissent, et sont migrés vers `lib/`, `funcs/` ou
|
||||
`tools/`, d'autre échouent et restent trainer dans le coin en attente
|
||||
du retour de l'inspiration.
|
||||
|
||||
Le contenu de ce répertoire doit donc être considéré comme
|
||||
**volatile**. Si vous y trouvez votre bonheur, il serait sage
|
||||
d'en faire une copie personnelle...
|
||||
|
||||
## MNT
|
||||
|
||||
Modèles numériques de terrain. Rien ne marche. Plein de maths.
|
||||
Un [code](mnt.c) complexe.
|
||||
|
||||
## fimg2obj
|
||||
|
||||
Création d'un fichier .OBJ (de Wavefront) à partir d'une image
|
||||
flottante afin d'avoir des vues en 3d pertinentes, bien qu'assez
|
||||
futiles.
|
||||
|
||||
## système de cache
|
||||
|
||||
`new: Mon Jul 17 12:49:20 UTC 2023`
|
||||
|
||||
En cours : définition d'à peu-près tout ce qu'il reste à faire
|
||||
pour avoir quelque chose qui fonctionne.
|
||||
Plus d'information dans le [.h](cachengn.h).

# Fonctions
|
||||
|
||||
Plein de fonctions qu'il serait bon de documenter :)
|
||||
|
||||
|
||||
## Contours
|
||||
|
||||
Détecter des contours est une activité respectable. Mais difficile.
|
||||
Une recherche dans la littérature s'impose.
|
||||
|
||||
## Exporter
|
||||
|
||||
`fimg_exporter` est une méta-fonction qui va sauvegarder (dans la mesure de ses conséquences)
|
||||
une image en fonction de l'extension du nom de fichier fourni.
|
||||
|
||||
### PNG
|
||||
|
||||
__Attention__ : la bibliothèque `pnglite` actuellement utilisée pour lire
|
||||
les fichiers PNG n'accepte que certains types de fichiers.
|
||||
Et en particulier, elle brotche sur ceux produits par ImageMagick !
|
||||
|
||||
### FITS
|
||||
|
||||
Ce [format de fichier](https://heasarc.gsfc.nasa.gov/docs/software/fitsio/c/c_user/node1.html)
|
||||
est utilisé en astronomie.
|
||||
Son support est actuellement minimaliste.
|
||||
|
||||
|
||||
### DICOM
|
||||
|
||||
https://en.wikipedia.org/wiki/DICOM et ça semble bien compliqué,
|
||||
donc ça reste pour le moment au stade de vague projet :(
|
||||
|
||||
## Sfx
|
||||
|
||||
Effets spéciaux divers. Ils sont répartis dans plusieurs fichiers
|
||||
(`sfx[0-4].c`) sans raison de classement apparente.
|
||||
|
||||
Certains peuvent être directement utilisés
|
||||
avec l'outil [../tools/fimgfx.c](fimgfx).
|
||||
Leur paramétrage est trop sommaire.
|
||||
|
||||
La fonction `fimg_pixelize_h_rnd` est issue d'une idée qui m'est venue
|
||||
dans la roulotte de TerreBlanque. Elle a besoin de recherches sur la
|
||||
dynamique temporelle, et d'une FSM à trois états.
|
||||
|
||||
## Dithering
|
||||
|
||||
Work in progress...
|
||||
|
||||
Une difficulté dans ce domaine, c'est la *floattitude* des pixels,
|
||||
sur laquelle il est difficile d'appliquer des operations binaires,
|
||||
comme le XOR.

# Floatimg, the base/core library

## 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.
|
||||
|
||||
```
|
||||
#define MAGIC_FIMG 0x00F11F00
|
||||
typedef struct {
|
||||
uint32_t magic;
|
||||
int width;
|
||||
int height;
|
||||
int type;
|
||||
float fval;
|
||||
int count;
|
||||
float *R, *G, *B, *A;
|
||||
FimgMetaData mdatas; // added 20230912
|
||||
int reserved;
|
||||
} FloatImg;
|
||||
```
|
||||
For the current state of this struc, look at the main
|
||||
[header file](../floatimg.h), located at the root of the project.

Comment générer des videos psychotiques avec un peu de bash.

Ce script est expliqué dans la documentation PDF.

|
||||
## 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.

# Fonctions
|
||||
|
||||
Plein de fonctions qu'il serait bon de documenter :)
|
||||
|
||||
## PNG
|
||||
|
||||
__Attention__ : la bibliothèque `pnglite`actuellement utiilsée pour lire les
|
||||
fichiers PNG n'accepte que **certains** types de fichiers.
|
||||
Et en particulier, elle brotche sur ceux produits par ImageMagick !
|
||||
|
||||
## Contours
|
||||
|
||||
Détecter des contours est une activité respectable.
|
||||
|
||||
## Exporter
|
||||
|
||||
Une méta-fonction qui va sauvegarder (dans la mesure de ses conséquences)
|
||||
une image en fonction de l'extension du nom de fichier.
|
||||
|
||||
## Sfx
|
||||
|
||||
Effets spéciaux divers.
|
||||
|
||||
## Dithering
|
||||
|
||||
Work in progress...
