I am working on a presentation in beamer and would like to put a logo in the background of the title page with a gradient fade-out effect, similar to the image below. The logo is in PDF format and is in full-shape.

You can achieve a similar effect on your personal logo in application such as Illutrator of Inkscape. This is not done directly within beamer. –  pluton Nov 27 '13 at 8:42

Sure, though I am under impression that it can also be done using TikZ quite simply. –  Ali Nov 27 '13 at 8:45

With WriteLaTeX's frog.jpg, also in https://www.writelatex.com/542861kyqykv

\documentclass{beamer}
\usetheme{Warsaw}
\usepackage{tikz}
\usetikzlibrary{fadings}


\setbeamertemplate{background}{%
\begin{tikzpicture}
\path (0,0) rectangle (\paperwidth,\paperheight);
\node[scope fading=west,inner sep=0pt,outer sep=0pt,anchor=north east] at(\paperwidth,\paperheight) {\includegraphics[height=\paperheight]{frog.jpg}};
\end{tikzpicture}
}

\author{Kermit}
\title{Autobiography}
\begin{document}
\maketitle

\end{document}

Your answer reminds of that question: tex.stackexchange.com/questions/112538/…. Would there be a way of superimposing multiple facings in different directions? –  Jubobs Nov 27 '13 at 10:07
    
@Jubobs Should be possible within a transparency group. –  percusse Nov 27 '13 at 15:14
