Sample placement in DBE / Colocación de muestras en DBE

[David Serrano]

Hi people,

In two words, if PixInsight isn't a program for processing astronomical images, why does DA desperately insist on searching "stars"? . I'm trying to join several panoramic images into a larger one and it's really hard to align trees, buildings, antennas, clouds and so on...

Must I have to use another software, that lets me specify the exact coordinates of the align points? (hugin seems like a good choice).

Edit: replaced "DBE" with "DA".


Hola chicos,

En dos palabras, si PixInsight no es un programa de procesamiento de imágenes astronómicas, ¿por qué DA se empeña desesperadamente en buscar "estrellas"? . Estoy intentando juntar varias imágenes panorámicas en una más grande y no hay manera de alinear árboles, edificios, antenas, nubes y demás...

¿Tendré que usar otro programa que me permita decirle las coordenadas exactas de los puntos a alinear? (hugin parece una buena opción).

Edito: he cambiado "DBE" por "DA".

And who told you that?  :lol:

I assume you're talking about DynamicAlignment (DA), not DBE. Indeed DA works by finding centroids of stars (or stellar like features) in the image, then using them as registration references.

Must I have to use another software

Heaven forbids  

A bit of patience is what I ask (hmmm, where did I hear this before?). I'm working hard on an automatic image registration (and mosaicing) system. It can work with stars as reference points, as well as corners (I'm using a SUSAN corner detector with good results), both detected automatically. The registration uses a fully projective model (eight parameters) so it is capable of translation, rotation, scaling, tilting and keystoning.
