Systems and methods for acquiring photoplethysmographic (PPG) signals for measuring blood pressure can include a computing device acquiring a sequence of images representing transdermal optical data of a subject, and generating a corresponding sequence of downsampled color frames. The computing device can identify, in each downsampled color frame, a respective central image block representing a central image region of the downsampled color frame and having a first size smaller than a second size of the downsampled color frame. The computing device can generate, for each downsampled color frame, a corresponding color intensity value based on the respective central image block. The computing device can generate, using color intensity values corresponding to the sequence of downsampled color frames, a PPG signal to determine a blood pressure value of the subject.

Provided is a smart insole including a support layer; a plurality of pressure sensors provided to the support layer and configured to sense a pressure; a plurality of vibrators provided to the support layer and configured to generate a vibration; and a controller configured to determine a center of pressure (COP) based on a pressure sensed by each of the plurality of pressure sensors and to control the plurality of vibrators based on a positional relationship between a setting point and the COP.

The present disclosure discloses a quantitative evaluation system and evaluation method for hemangioma. The evaluation system includes an image acquisition module, an image analysis module, a result evaluation module and a display module. The image acquisition module includes a light source device, an imaging device and a storage device. The image analysis module includes a digital signal processor and digital analysis software.
