More flagship phones on the horizon: Xiaomi's 12 Series gets a global launch


Xiaomi announced its flagship 12-series smartphones in China towards the end of December 2021, and has now given the three new handsets – Xiaomi 12 Pro, Xiaomi 12 and Xiaomi 12X – a global launch. The 12 Pro and 12 phones are based on Qualcomm's top-end 4nm Snapdragon 8 Gen 1 chipset, while the 12X is powered by the less powerful but more power-efficient 7nm Snapdragon 870 5G mobile platform. The 12-series phones employ what Xiaomi calls a'high-performing cooling system' including a'super large' vapour chamber and multiple layers of graphite. All three devices have 120Hz AMOLED displays (6.73 inches on the 12 Pro and 6.28 inches on the 12 and 12X), with 12-bit colour support – that's 68.7 billion colours – available on the two 6.28-inch devices. There are triple rear camera arrays across the board, and Xiaomi is highlighting advances in AI-assisted photography and videography with the 12-series phones.

Camera Invariant Feature Learning for Generalized Face Anti-spoofing Artificial Intelligence

There has been an increasing consensus in learning based face anti-spoofing that the divergence in terms of camera models is causing a large domain gap in real application scenarios. We describe a framework that eliminates the influence of inherent variance from acquisition cameras at the feature level, leading to the generalized face spoofing detection model that could be highly adaptive to different acquisition devices. In particular, the framework is composed of two branches. The first branch aims to learn the camera invariant spoofing features via feature level decomposition in the high frequency domain. Motivated by the fact that the spoofing features exist not only in the high frequency domain, in the second branch the discrimination capability of extracted spoofing features is further boosted from the enhanced image based on the recomposition of the high-frequency and low-frequency information. Finally, the classification results of the two branches are fused together by a weighting strategy. Experiments show that the proposed method can achieve better performance in both intra-dataset and cross-dataset settings, demonstrating the high generalization capability in various application scenarios.

MWC 2019: ZTE announces Axon 10 Pro 5G smartphone


Chinese tech giant ZTE has announced its 5G flagship smartphone at Mobile World Congress (MWC) 2019, with the Axon 10 Pro 5G to launch in China and Europe by June 2019. The first 5G smartphone from the company packs a Qualcomm Snapdragon 855 mobile platform, a Snapdragon X50 5G modem, and an artificial intelligence (AI) engine that automatically adjusts CPU, GPU, RAM, and ROM using AI algorithms. AI capabilities are also used across the triple camera, motion capture, scene recognition, portrait lighting adjustment, and for learning user behaviour. The smartphone operates on sub-6GHz spectrum frequencies. "The latest addition to ZTE's premium flagship Axon series also implements a fully self-developed, full-band antenna design to achieve full coverage of 2G/3G/4G/5G and effectively improved system performance by reducing signal interference," ZTE said in Barcelona on Monday.

Huawei Mate 10 Pro is an AI-powered phone with a unique design


China's top smartphone maker, Huawei, has recently overtaken Apple in global smartphone sales and it's second just behind Samsung. But with their new, most ambitious smartphone yet -- the Mate 10 -- the Chinese company is finally ready to take on the competition from all sides. The first thing that really strikes you about the Mate 10 and its more powerful variant, the Mate 10 Pro, is the snazzy, sleek, compact design, particularly compared with the past models. Both the Mate 10 and Mate 10 Pro have an aluminium frame, glass back and front which is slightly bent around the edges and really slim bezels on top and bottom. On the back, the Leica-branded vertical dual-camera module is encased in a horizontal strip that is in a lighter colour compared to the rest of the phone.

Meitu's latest smartphone is for the selfie-obsessed


By now, you would've heard of Meitu -- the top Chinese beautifying app that's taking the world by storm. The Chinese app maker is also capitalising on the selfie-obsessed with its range of "selfie phones." SEE ALSO: China's latest beauty app takes Snapchat-style filters to the extreme Its latest model, the T8, was just announced on Tuesday, and has placed fast autofocus 12 megapixel cameras on both front and back. The cameras use a dual pixel Sony IMX362 sensor -- the same sensor used for the rear camera of the Xiaomi Redmi Pro 2. Dual pixel cameras are touted to provide much faster autofocus, as well as clearer low-light pictures. The phone's built in beautifying software will also bring some form of artificial intelligence to the table, the company claims.
