Shining Bright: The Golden Era of Signal Processing
T
hree years ago, I wrote my inaugural editorial, “Embracing a New Golden Age of Signal Processing,” [1] for our IEEE Signal Processing Magazine (SPM). Today, while writing this farewell editorial and in representing our entire SPM editorial team, I can proudly say the golden era has not only arrived for us to embrace and celebrate, but it is also shining bright and is here to stay. My service for SPM started in 2004, when Prof. Ray Liu, then editor-in-chief, invited me to be the lead guest editor for a special issue. Since then, SPM has been a main focus of my service to the IEEE Digital Object Identifier 10.1109/MSP.2011.942544 Date of publication: 1 November 2011

wide range of SP-enabled future wants and needs (e.g., [4]). In my own work environment within a major computer software company, SP methods and applications as defined in the expanded scope had also permeated every corner. Our community had clearly come to realize that while SP played an integral part in the technological development of television, telephone, communication, multimedia, space travel, and computers, more exciting challenges and opportunities would lie ahead for SP in broad areas such as intelligent communication; natural human-machine interface; universal language translation; biomolecular information processing; automated navigation; efficient generation/ distribution/consumption of “green” energy; intelligent sensor and human
Signal Processing Society (SPS) and to the SP community. When working as an editorial board member and area editor under the leadership of my predecessor, Prof. Shih-Fu Chang, I witnessed the immeasurable vibrancy, invigorating energy, and unbounded intellectual landscape of our SP community. During 2007–2008, with Prof. Chang’s guidance, I initiated the effort in expanding the scope and technical fields of SP [2]. This led to substantial broadening of the article coverage in SPM along the two axes of “signal” and “processing” [3]. In the meantime, while helping Prof. Chang to solicit potential articles for SPM, I interacted with several pioneers in various technical areas pertinent to SP. These interactions provided me with the opportunity to learn, analyze, and appreciate a

networks; global financial market analysis; and much more [4], [5]. All these, together with the numerous SPempowered technological advancements—e.g., mobile devices becoming ubiquitous, multicore and cloud computing going mainstream, Web search turning intelligent—already brewing in the midst of economic recession three years ago, heralded a new tech boom and a bright era ahead in our field of SP. Indeed, during the past three years, we have witnessed tremendous growth in signal processing at the global scale. I was honored to lead an energetic, diligent, creative, and productive editorial team to embrace the vitality of our SP community in this golden age. The magazine served not only as an educational tool but also as a catalyst in advancing SP technology. Our articles exemplified and embodied technical rigor and new trends of SP as well as the extraordinary variety of SP applications in our daily lives and their societal impact. Our editorial team took a unique approach to running SPM. We took risks, pushed the limit, and we were eager to innovate and try things that had never been done before. We embraced the motto that it is more fun being movers and shakers than being followers and being incremental. We held the attitude that if we fail, let it be, but if we succeed, we would win big. (Don’t we all run research groups and do SP research in the same way?) One significant innovation we engendered over the past two years is the translation editions of SPM into Chinese and Brazilian Portuguese, where we saw huge emerging SP engineering bases and potential explosive readership growth. This is the first time in history that IEEE publications have done a Chinese translation. References [6]–[10] are just a few examples of a larger pool of the articles we have translated to Chinese and Brazilian Portuguese. We listened closely to our readers’ feedback in Asian-Pacific countries and published side-by-side English-Chinese translation. This enables them not only to read the technical content more efficiently in their native language, but more importantly, to write better SP articles in
English. To accommodate the difference between simplified and traditional Chinese styles that are both popular in Asian-Pacific countries, we created a three-column glossary for technical terms of SP in English and in the corresponding simplified and traditional Chinese pairs. As an example of the impact of this “side” glossary project within our much larger translation project, we are looking at extending our approach to all IEEE-relevant technical terms that are far beyond the scope of SP. Another important innovation we have created and pushed hard is the use of Tag for direct and convenient access to multimedia supplementary material via smartphones, which can go with the readers everywhere. It opens a new way of linking and integrating the printed material with the author-created online content. It also opens a new opportunity for creative design of the online supplementary material (e.g., animated figures that would drastically enhance the current static figures in print and the “justin-time” contextual appendix, references, or video/audio/handwriting tutorials, etc.). Other notable innovations we have instituted include the (ongoing) crossSociety collaboration to attract wider audiences, digital delivery of our articles, special issues focusing on emerging SP applications [5], and publications of unique types of articles. Examples of the latter are the articles reporting vastly visible SP applications (e.g., [11] and [12]), highlighting research directions (e.g., [13]–[15]), analyzing technical trends and their future (e.g., [4] and [15]), and focusing on SP education or history with a lecture-note style (e.g., [16]–[20]). Our approach turned out to be quite successful. In the latest IEEE Annual Report, our Chinese translated edition of SPM is prominently featured with the following strong endorsement: … The first IEEE publication in Chinese, this special issue of IEEE Signal Processing Magazine was distributed in 2010 at the Society’s International Conference on Image Processing in Hong Kong. … This Chinese translation is the first step in the Society’s efforts to enhance
its visibility among non-English speaking audiences. …SPM ranks highest among all electrical and electronic engineering journals. In the summers of 2010 and 2011, SPM’s accomplishments were reflected in Thomson Reuters’ Journal Citations Reports (JCR), generally accepted as the world’s most influential source of information about peer-reviewed publications. SPM’s impact factor has dramatically increased from 3.76 in 2008 (ranked ninth; see the comparison group below) to 4.91 in 2009 (moved to first place) and further to 5.86 in 2010 (continues to rank first). Comprehensive compilation in the JCR results shows that our SPM’s top rank is among all publications in the broad electrical and electronics engineering field (247 of them in total, including 147 of IEEE’s) the two most recent years in a row. The five-year long-term impact factor of SPM also jumped from 5.95 (in 2009) to 6.89 (in 2010) as a result of highly cited, most recent SPM articles. Further, the Article Influence Score of SPM continues to rank number one among the 247 journals, again two most recent years in a row—2.48 in 2009, jumping to 3.18 in 2010. This is an outstanding record and an honor brought to our Society and community, which in turn validates our novel approach to running SPM. Behind the success and top-ranking honor are the real heros: our editorial team members. I thank them for taking the journey with me in our relentless pursuit of excellence and in pushing the boundaries of innovation in running our SPM. Area Editors Dan Schonfeld (special issues), Antonio Ortega (feature articles), Ghassan AlRegib (column/forum), and Jane Wang (together with Min Wu, as e-newsletter area editors) deserve special recognition and appreciation. Their dedicated service, infectious enthusiasm, and selfless sacrifice over the past three years have made our SPM what it is today. They, together with their associate editor teams, have been tirelessly working with me towards the common and clear goal of making SPM the best among the best. Thanks also go to our SPM editorial board for their guidance in reviewing white papers, providing feedback, and
