What's your internal signal-to-noise ratio? - David Otey at TEDxBillings
Noise can take many forms. Even in the relative quiet of Montana, where we may be able to escape physical noise, it is not always possible to still our minds and quiet the "chattering monkeys." As a depression survivor, I have learned first-hand the importance of paying careful attention to the thoughts and messages I allow free rein in my mind. The engineering concept of "signal-to-noise ratio" -- tune in what's good, filter out as much as possible of what's not -- is a useful metaphor for describing the process of emotional self-care. David P. Otey, MA, MBA, brings a unique blend of education, eloquence, and experience to the platform. Armed with degrees in physics, communication, and broadcasting management, he pursued a successful career in television engineering, where he relished leading others to their own "ah-ha!" moments by taking challenging concepts and making them understandable. In 2007, his passion for learning propelled him to the head of a training effort that was unprecedented in the television industry, reaching over 10,000 broadcasting technicians in a three-year period. In 2011, Otey formed a new company, Speaking of Solutions, LLC, with a focus on helping individuals and organizations identify and move past resistance to change. With his own story -- technology expert reinvented as trainer/motivator -- as background, and a core message that is well-grounded and research-based, he has inspired audiences to examine their assumptions, filter out the noise, and embrace a growth mindset. In the spirit of ideas worth spreading, TEDx is a program of local, self-organized events that bring people together to share a TED-like experience. At a TEDx event, TEDTalks video and live speakers combine to spark deep discussion and connection in a small group. These local, self-organized events are branded TEDx, where x = independently organized TED event. The TED Conference provides general guidance for the TEDx program, but individual TEDx events are self-organized.* (*Subject to certain rules and regulations)- published: 19 Mar 2014

how to calculate PSNR Peak Signal To Noise Ratio in Digital Image Processing
how to calculate PSNR Peak Signal To Noise Ratio in Digital Image Processing
The peak signal-to-noise ratio (PSNR) is the ratio between a signal's maximum power and the power of the signal's noise. Engineers commonly use the PSNR to measure the quality of reconstructed images that have been compressed. Each picture element (pixel) has a color value that can change when an image is compressed and then uncompressed. Signals can have a wide dynamic range, so PSNR is usually expressed in decibels, which is a logarithmic scale. Items you will need Calculator with statistical functions Step 1 Define the bel and decibel. The bel is defined mathematically as LB = log10 (P1/P0) where P1 and P0 are two quanties that are in the same units of measure. The decibel is 0.1 bel, so the decibel value LdB is LdB = 10 log10 (P1/P0). Step 2 Define the mean squared error (MSE) between two monochromatic images, where one image is considered to be an approximation of the other. The MSE can be described as the mean of the square of the differences in the pixel values between the corresponding pixels of the two images. Step 3 Express MSE mathematically from the description in Step 1. We therefore have MSE = 1/mn [ΣΣ (I(i,j) - K(i,j))^2] where I and K are matrices that represent the images being compared. The two summations are performed for the dimensions "i" and "j." Therefore I(i,j) represents the value of pixel (i,j) of image I. Step 4 Determine the maximum possible value of the pixels in image I. Typically, this may be given as (2^n) - 1 where n is the number of bits that represent the pixel. Thus, an 8-bit pixel would have a maximum value of (2^8) - 1 = 255. Let the maximum value for pixels in image I be MAX. Step 5 Express the PSNR in decibels. From Step 1, we have the decibel value LdB as LdB = 10 log10 (P1/P0). Now let P1 = MAX^2 and P0 = MSE. We then have PSNR = 10 log10(MAX^2/MSE) = 10 log10(MAX/(MSE)^(1/2))^2 = 20 log10(MAX/(MSE)^(1/2)). Therefore, PSNR = 20 log10(MAX/(MSE)^(1/2)). http://classroom.synonym.com/calculate-psnr-2653.html- published: 02 Nov 2013
