I have been trying my hand at Amazon's Mechanical Turk - scouring imagery in search of missing Microsoft Research guru Jim Gray. Dr. Gray is the father of TerraServer and many other groundbreaking pursuits at Microsoft. Coast Guard efforts to date have been fruitless, as the story continues to unfold. Through a collaborative effort, recent imagery of the search area has been posted on Amazon's Mechanical Turk, in the hopes that signs of his 40-foot sailboat, life rafts or any other signs can be found, in a collaborative effort.
It is somewhat challenging, as image resolutions and scene conditions for the images I have had are not optimal for finding a 40-foot sailboat, let alone smaller features, such as a liferaft, but it is good to see that efforts like Mechanical Turk are becoming available toward organizing massive human effort toward detection and other tasks.
My hopes and prayers remain with Dr. Gray's family, friends and colleagues.
