Abstract: The present disclosure relates to an image segmentation method based on a chrominance component. The method includes the following steps: obtaining a chrominance component of an image; generating a chrominance component histogram according to the chrominance component; determining peaks and troughs in the chrominance component histogram according to a preset chrominance interval and preset peak and trough setting conditions; obtaining a segmentation threshold according to the peaks and the troughs; and segmenting the image into a plurality of regions with different chrominances according to the segmentation threshold. In the present disclosure, the segmentation threshold is obtained according to the peaks and the troughs, the segmentation threshold is dynamically adjusted according to different images, and a fixed segmentation threshold is not used, thereby effectively reducing false segmentation.

Abstract: A giant magnetoresistance (GMR) sensor is formed using a self organizing diblock copolymer as an etching mask. The diblock copolymer is deposited over a magnetic layer and is self organized into regions of two discrete thicknesses; higher thickness island regions separated by lower thickness valley regions. After the diblock layer is self organized, an etching of process is performed to remove the polymer material from the valley regions as well as the underlying magnetic material. After etching, a patterned magnetic thin film of submicron islands of magnetic material, preferably having a diameter in the single domain range, remain under the mesa region. The islands are interconnected by a non-magnetic, conductive layer with electrical contacts coupled thereto to complete the GMR sensor. When the sensor is not subjected to a magnetic field, the magnetic alignment of the islands is random, and electron scattering results in a high resistance state.

Abstract: The present invention is polymer blend, which includes at least two immiscible polymers, and a compatibilizer used to produce a substantially homogeneous blend. The compatibilizer is a functionalized nanocomposite which prevents segregation of the polymer components in the polymer blend. The nanocomposites are formed by combining an organoclay and an intercalation agent. The intercalation agent is a reaction product of a polyamine functionalized with an alkyl halide in a polar solvent. The compatibilized blends are used in thin films, which are especially useful in microlithographic applications and as lubricants in low tolerance magnetic disks.
