Dietary intake provides valuable insights for mounting intervention programs for prevention of disease [1, 2]. However, accurate assessment of diet is problematic. Immerging technology in mobile telephones (cell phones) with higher resolution images, improved memory capacity, and faster processors, allow these devices to process information not previously possible. To adequately address these challenges, we further describe enhancements to a novel dietary assessment system we are developing using a mobile device (e.g. a mobile telephone or pda-like device) to provide an accurate account of daily food and nutrient intake [3].
Our goal is to use a mobile device with a build-in camera, network connectivity, integrated image analysis and visualization tools with a nutrient database, to allow a user to discretely record foods eaten. Mobile devices, such as PDAs and mobile telephones with cameras, are general purpose computing devices that have a great deal of computational power that can be exploited for solutions to this problem. Mobile computing devices provide an unique vehicle for collecting dietary information [3]. Images of food can be marked with a variety of input methods that link the item for image analysis to estimate the amount of food. Images acquired before and after foods are eaten can estimate the amount of food consumed [3].
Disinflation programs set in motion in the 1980s have enjoyed great success across both industrial and developing economies. Price stability, defined as low and stable inflation, has become a widespread reality. Central bank (CB) independence is now firmly enshrined in the legal framework of most industrial economies, and the credibility of central bankers engaged in rule based policy making has been greatly enhanced.
Hardly did the celebrations of the demise of the “Great Inflation” begin when the alarm of a deflationary spiral sounded and the fear of the economies hitting the zero lower bound (ZLB) on nominal interest rates and of falling into the infamous “liquidity trap” began to trouble the minds of many central bankers around the world. The decade-long “Great Recession” of Japan and the recent economic slowdown in the US and in some major European economies, combined with very low and occasionally negative inflation rates, raised the specter of a new era of deflationary recessions and of a loss of monetary policy effectiveness in an environment of price stability.
