The Int’l Symposium on Image and Signal Processing and Analysis (ISPA 2015) will be held in Zagreb, Croatia from 7-9 September 2015. This change is due to unexpected organizational difficulties encountered by the organizers in Edinburgh, UK. We apologize for any inconvenience this change may have caused. Welcome to the web site of the ISPA 2015 symposium. ISPA 2015 will be organized in Zagreb, the capital city of the Republic of Croatia. Zagreb is an old Central European city. For centuries it has been a focal point of culture and science, and now of commerce and industry as well. It lies on the intersection of important routes between the Adriatic coast and Central Europe. Zagreb is also the hub of the business, academic, cultural, artistic and sporting worlds in Croatia. Zagreb can offer its visitors the Baroque atmosphere of the Upper Town, picturesque open-air markets, diverse shopping facilities, an abundant selection of crafts and a choice of vernacular cuisine. Zagreb is a city of green parks and walks, with many places to visit in the beautiful surroundings. ISPA 2015 is an international symposium that brings together researchers from many countries, serves as a forum for exchange of new ideas, and promotes international research collaboration.
