This class can be used to determine whether an image may contain nudity.

It analyses the colors used in different sections of an image to determine whether those colors match the human skin color tones.

As result of the analysis it returns a score value that reflects the probability of the image to contain nudity.

Additionally, it can output a the analysed image marking the pixels with color skin tones with a given color.

Currently it can analyze images in the PNG, GIF and JPEG images.

Prize: One book of choice by SAMS		 The widespread availability of nudity pictures is a great concern, especially for parents with young children.

Determining whether a picture contains nudity is also a concern for sites that ban such kinds of pictures. Often they do not have enough human resources to monitor all pictures submitted by the site users.

This class provides a solution that can help determining whether a picture may contain nudity.

It analyses the colors and shapes of the objects in a picture and gives a score value that may help picture content moderators to reduce the search for undesired nudity pictures.

Increible pero cierto, una clase que nos dice si hay gente desnuda en una imagen. Esta clase analiza los colores y las formas de los objetos en una imagen y devuelve una puntuación de probabilidad de desnudos en la imagen.
Pareciera imposible pero lo cierto es que se ha publicado una clase en php que lo que hace es detectar los colores de la imagen y devuelve un resultado del grado evaluado, muy util para el uso de filtros de imagenes, me gustaria dar un ejemplo :P, saludos...

Ahora que está tan de moda el software social y las posibilidades de compartir nuestras experiencias, sobre todo en imágenes. Es posible que no queramos que los usuarios suban imágenes con desnudos. Para ello esta clase que analiza los colores...
I have no idea how to implement this, but it looks like it is possible to have your browser detect nude images without looking at the filename, but scanning the actual image…uuhhmm..yeah.. check it here.

I generally just delete the email that comes from PHPClasses.org summing up what updates have been done and what new code is out there. It’s not because I don’t value the classes that are on the site. Quite the contrary. There is some really excellent PHP code on the site...
