Abstract: An animation generation method for tracking a facial expression and a neural network training method thereof are provided. The animation generation method for tracking a facial expression includes: driving a first role model according to an expression parameter set to obtain a virtual expression image corresponding to the expression parameter set; applying a plurality of real facial images to the virtual expression image corresponding to the facial expression respectively to generate a plurality of real expression images; training a tracking neural network according to the expression parameter set and the real expression images; inputting a target facial image to the trained tracking neural network to obtain a predicted expression parameter set; and using the predicted expression parameter set to control a second role model.

Abstract: A water treatment device includes a case having an inlet fitting on an underside thereof and a plurality of cylinders overlapped and received in the case. Each cylinder has a tube received therein and four first ribs connected between the tube and an inner periphery of the cylinder so as to define four first partitions for respectively receiving four curved magnetic pieces therein. Three second ribs are located in each tube and define three second partitions in each tube and each second partition has a plurality of mineral particles received therein. A first one of the three second ribs has an upper notch defined in a top edge thereof and a second one of the three second ribs has a bottom notch defined in a bottom edge thereof. A plurality of holes are defined through an area of the closed end of each cylinder and the area is located between the first one of the three second ribs and a third one of the three second ribs.

Abstract: A water treatment device includes a case having an inlet fitting on an underside thereof and a plurality of bulks overlapped and received in the case. Each bulk has a tube received therein and three first ribs connected between the tube and an inner periphery of the bulk so as to define three first partitions for respectively receiving three curve magnetic piece therein. Three second ribs are located in each bulk and define three second partitions in each tube and each second partition has a plurality of mineral particles received therein. A first one of the three second ribs has an upper notch defined in a top edge thereof and a second one of the three second ribs has a bottom notch defined in a bottom edge thereof. A plurality of holes are defined; through an area of the close end of each bulk and the area is located between the first one of the three second ribs and a third one of the three second ribs. A water tank is located at a top of a row of the bulks and has a water permeable close end.

Abstract: A water treatment device includes four filtering members connected in series and the filtering members include a porous film, an active carbon, a ceramic tank or magnets and porous objects. The magnets activate the water and the mineral substances can be solved in the water.
