  • Patent number: 10984506
    Abstract: An image anti-aliasing method comprises following steps: receiving an aliasing image; wherein the aliasing image includes a plurality of source pixels; generating a plurality of hash values corresponding to the plurality of source pixels respectively; and performing a filtering processing or a filter generating procedure on the aliasing image according to the plurality of hash values. Each of the plurality of hash values is generated by the following steps: selecting one source pixel from the aliasing image and selecting a window containing the selected source pixel; determining an aliasing strength according to the grayscale values of all the source pixels of a row and a column at which the selected source pixel is located in the window; and determining a hash value of the selected source pixel according to the aliasing strength.

  • Publication number: 20150377256
    Abstract: A drainage system includes a water pump body, a water pump body water inlet pipe, a water outlet pipe, a water storage apparatus and a connection fastener. The connection fastener is connected to the water inlet pipe and the water outlet pipe, the water inlet pipe and the water outlet pipe are being joined embedded to form an annular cavity. The inside of the annular cavity includes a filter, the periphery of the filter having a locating ring, the cross-section width of the locating ring is greater than the spacing between the front end surface of the connection fastener and a stop surface, and the connection fastener includes a clamping apparatus. If a user forgets to mount the filter, the annular cavity between the water inlet pipe and the water outlet pipe makes the connection between the water pump and the water storage apparatus unstable.
