Systems and methods are disclosed for dynamically smoothing images based on network conditions to adjust a bitrate needed to transmit the images.

In other words, a region of an image showing a grassy lawn has a high frequency of variation from pixel to pixel resulting from the fine detail of separate blades of grass that may be similar in color, but not homogeneous. Encoding the region as a single shade of green (or multi-pixel regions of different shades of green) enables a viewer to recognize it as a grassy lawn while greatly reducing the number of bits needed to represent the region. |

An information processing apparatus generates a command for a communication terminal apparatus and a retry command and successively outputs the generated command and retry command to an information processing terminal apparatus. The information processing terminal apparatus acquires the command for the communication terminal apparatus and the retry command that have successively been output from the information processing apparatus and outputs the acquired command to the communication terminal apparatus. Further, in a case of performing a retry process due to unavailability of a response to the command, the information processing terminal apparatus outputs the acquired retry command to the communication terminal apparatus. The retry process can be performed without waiting for the information processing terminal apparatus to output a command request to the information processing apparatus and acquire a retry command. Accordingly, a process between a communication terminal apparatus and an information processing apparatus via an information processing terminal apparatus can be performed efficiently. |

Skin personal identification (Skin-PIN)
Traditionally, biometrics provides identification based on fingerprints, iris, or face to a vendor. The vendor's database can be hacked or a person's traditional biometrics can be stolen or compromised. Because an individual has only FFten fingers and two eyes, if compromised, secure identification becomes very difficult. A new approach for personal identification, leveraging “skin” biometrics, offers protection for individuals, and provides the ability to change their biometric identity by selecting a different patch of skin to use as skin identification. The biometric method and system provides biometric identification based on a small section of a person's skin. Skin biometrics is leveraged for positive identification of individuals. Skin biometrics captures a region of the subject's skin topography, then maps surface landmarks, creating a unique result that the user can provide in various authentication scenarios. The Skin-PIN combines with the virtually limitless possibilities of skin areas on the body of a user. |

Higher quality diffusion metrics and/or diffusion-weighted images are generated from lower quality input diffusion-weighted images using a suitably trained neural network (or other machine learning algorithm).
