The present invention is a computer-implemented system and method for transforming video data into directional object counts. The method of transforming video data is uniquely efficient in that it uses only a single column or row of pixels in a video camera to define the background from a moving object, count the number of objects and determine their direction. By taking an image of a single column or row every frame and concatenating them together, the result is an image of the object that has passed, referred to herein as a sweep image. In order to determine the direction, two different methods can be used. Method one involves constructing another image using the same method. The two images are then compared, and the direction is determined by the location of the object in the second image compared to the location of the object in the first image. Due to this recording method, elongation or compression of the objects can occur because of acceleration or deceleration of the objects and can be uniquely utilized to determine the speed or movement path of the objects. The second method of determining direction involves comparing the object in the image to an established marker. The transformations can also be used to produce labeled data for training machine learning models: bounding-boxes provided in sweep image can be transformed to bound boxes in video, and boxes in video can be transformed into boxes in the sweep image.

The present disclosure generally relates to reducing time for interface transmitter training based upon an assumed identify of the training partner. It is unlikely for a drive PHY to link up with multiple PHYs per power cycle. Therefore, it is a fair assumption that when there is no power loss, the drive PHY is connected to the same host device. The drive can therefore change its behavior based on the assumed identity of the host from previously exchanged identify frames, if the previously used training algorithm was sufficient for interface transmitter training for the particular host. The drive will go directly to the correct training algorithm without the need to do a PHY reset using a training algorithm that is tailored to the host and thus reduce interface transmitter training time.
