Automatic ROI for remote photoplethysmography using PPG and color features  »
Remote photoplethysmography (rPPG) enables contact-less monitoring of the blood volume pulse using a regular camera, thus providing valuable information about the cardiovascular system. However, the quality of the acquired rPPG signal is strongly affected by the region of skin where the analysis is carried out and, therefore, to be confident of obtaining valid information, a pre-selection of the region-of-interest (ROI) for the PPG analysis is necessary. In this paper, we propose a method for the automatic extraction of this ROI combining the local characteristics of the PPG-signal with the color information using fuzzy logic. Results of the quality of the ROI extraction and its application on pulse rate detection are provided.

A Front-End ASIC for a 3-D Magnetometer for Space Applications by Using Anisotropic Magnetoresistors  »
This paper presents an application-specific integrated circuit (ASIC) aimed for an alternative design of a digital 3-D magnetometer for space applications, with a significant reduction in mass and volume while maintaining a high sensitivity. The proposed system uses magnetic field sensors based on anisotropic magnetoresistances and a rad-hard mixed-signal ASIC designed in a standard 0.35 μm CMOS technology. The ASIC performs sensor-signal conditioning and analogue-to-digital conversion, and handles calibration tasks, system configuration, and communication with the outside. The proposed system provides high sensitivity to low magnetic fields, down to 3 nT, while offering a small and reliable solution under extreme environmental conditions in terms of radiation and temperature.

Real-time single-exposure ROI-driven HDR adaptation based on focal-plane reconfiguration  »
This paper describes a prototype smart imager capable of adjusting the photo-integration time of multiple regions of interest concurrently, automatically and asynchronously with a single exposure period. The operation is supported by two intertwined photo-diodes at pixel level and two digital registers at the periphery of the pixel matrix. These registers divide the focal-plane into independent regions within which automatic concurrent adjustment of the integration time takes place. At pixel level, one of the photo-diodes senses the pixel value itself whereas the other, in collaboration with its counterparts in a particular ROI, senses the mean illumination of that ROI. Additional circuitry interconnecting both photo-diodes enables the asynchronous adjustment of the integration time for each ROI according to this sensed illumination. The sensor can be reconfigured on-the-fly according to the requirements of a vision algorithm.

A Procedure for Alternate Test Feature Design and Selection  »
This paper is a practical illustration of the adoption of alternate tests based upon the judicious selection of the set of parameters to be considered for design as well as to be observed subsequently. The notion of signatures is introduced, and their ability to predict design accuracy is analyzed. The application is demonstrated for an RF LNA circuit.

A 151 dB High Dynamic Range CMOS Image Sensor Chip Architecture With Tone Mapping Compression Embedded In-Pixel  »
This paper presents a high dynamic range CMOS image sensor that implements an in-pixel content-aware adaptive global tone mapping algorithm during image capture operation. The histogram of the previous frame of an auxiliary image, which contains time stamp information, is employed as an estimation of the probability of illuminations impinging pixels at the present frame. The compression function of illuminations, namely tone mapping curve, is calculated using this histogram. A QCIF resolution proof-of-concept prototype has been fabricated using a 0.35 μm opto-flavored standard technology. The sensor is capable of mapping scenes with a maximum intra-frame dynamic range of 151 dB (25 bits/pixel in linear representation) by compressing them to only 7 bits/pixel, while keeping visual quality in details and contrast. The in-pixel on-the-fly fully parallel tone mapping achieves high-frame rate allowing real-time high dynamic range video (120 dB at 30 frames/s).
