摘要： A thermal face and landmark detection method comprises:
providing a ground truth reference database,
capturing a thermal image (10) comprising at least one face (20);
detecting a face (21) in the thermal image (10);
cropping (30) the thermal image (10) creating a cropped face thermal image (35);
applying a Gaussian filters method (40) to the cropped face thermal image (35) creating an improved cropped face thermal image (45); and
applying a landmark detector (50) to the improved cropped face thermal image (45) creating an landmarked cropped face thermal image (55).-

摘要： A cross-spectral face recognition learning method according to the invention is based on a set of associated face images, a thermal image (10T) and a visual image (10V), of a plurality of persons. The thermal image (10T) is coded in two different ways. A style encoder (200T) provides a style code (420T) of the thermal image (10T). An identity encoder (100T) provides an identity code (410T) of the thermal image (10T). The visual image 10V is coded in a similar way with a style encoder (200V) providing a style code (420V) and with an identity encoder (100V) providing an identity code (410V). The two face images of the same person share in the identity features a common part in the respective identity codes (410T and 410V), noted as common identity code (410VT), whereas the style codes (420T and 420V) for the two images comprise features only relevant two the specific style, i.e. either thermal or visual, of the image.

摘要： The present invention provides a method or system of unveiling high-resolution visible face images from any low-resolution thermal face images can include inputting any number of thermal face images as an input through a generative adversarial network to perform spectrum translation of the low-resolution thermal face images to a number of high-resolution visible face images, training the generative adversarial network with at least a reference high resolution image, adapting or training the generative adversarial network for one or more among L1 loss, perceptual loss, and identity loss, and generating a high-resolution visible face image from any low-resolution thermal face images provided as an input to the generative adversarial network. In some embodiments, the method further adapts the generative adversarial network by further adapting or training for one or more among attribute loss and local loss. In some embodiments, the method simultaneously adapts for one or more of L1 loss, perceptual loss, identity loss, attribute loss and local loss.
