Abstract: A method for modifying a subtitle of a video frame. Subtitle text representing audio content of a video frame and font attributes of the subtitle text are received. A color of the subtitle text is identified, based on the font attributes of the subtitle text. A geometric region within the video frame corresponding to a display area of the subtitle text. A predominant color of the geometric region within the video frame is calculated. A level of similarity between the color of the subtitle text and the predominant color of the geometric region is determined. Rendering information of the subtitle text is calculated, based on the level of similarity, and a modification of the subtitle text is performed by applying the rendering information to the subtitle text, such that the modification reduces the similarity level during display of the video frame.

Abstract: A system enhances safety of a dependent person, if a caregiver inadvertently leaves the person unattended in a parked vehicle, by sending an escalating alarm sequence to the caregiver and/or other responsive parties. The system learns, via monitoring, a series of patterns associated with movements of a set of related mobile devices. The system continues to monitor, on an ongoing basis, the devices, and continually compares the current status of each one with its expected status based on the learned patterns. If the system detects a deviation between the current and expected status with respect to one or more of the devices, it computes an alarm level and a false positive score. If the combination of the alarm level and the false positive score is above a threshold value, the system initiates the alarm sequence. Note: a child should never be left unattended in a parked vehicle.
