In this paper, a method and algorithm of skeleton extraction based on binary mathematical morphology is presented. Sequential structuring elements (SEs) is also studied, which is the key problem of skeleton extraction. The examples of boiler flame image processing show that the detected skeletons can present the geometric shape of flame images well. 展开更多

言笑晏晏,不觉已是归处。回望那朵朵粉云,想起崔护的那句'人面不知何处去,桃花依旧笑春风。'愿明年初春复来之时,仍有幸到这里看这含羞带笑的花中仙子。诗人笔下,各种名贵花木不胜枚举,有艳丽的玫瑰、多姿的菊花、婀娜的荷花,... 言笑晏晏,不觉已是归处。回望那朵朵粉云,想起崔护的那句'人面不知何处去,桃花依旧笑春风。'愿明年初春复来之时,仍有幸到这里看这含羞带笑的花中仙子。诗人笔下,各种名贵花木不胜枚举,有艳丽的玫瑰、多姿的菊花、婀娜的荷花,以及牡丹、丁香、月季和海棠,然而在春暖花开的三月,我独爱那粉嫩嫩的桃花。桃花是三月的象征,是春天的象征。 展开更多

Two new different Cu(Ⅱ) MOFs with the same 1,3,5-tris(1-imidazolyl) benzene(tib) ligand {[Cu(tib)2]·(H2O)2·Br2}n(1) and {[Cu2(tib)·Br·Cl]·2Br}n(2) were obtained by one pot synthesized of tib ... Two new different Cu(Ⅱ) MOFs with the same 1,3,5-tris(1-imidazolyl) benzene(tib) ligand {[Cu(tib)2]·(H2O)2·Br2}n(1) and {[Cu2(tib)·Br·Cl]·2Br}n(2) were obtained by one pot synthesized of tib with CuBr in the presences of HCl and water. X-ray single crystal diffraction analyses indicate that both complexes 1 and 2 have two dimensional frameworks containing different building blocks. Each Cu(Ⅱ) atom in complex 1 is coordinated by four N atoms from different tib ligands. However, there are two different cryptographic Cu(Ⅱ) atoms in complex 2, one is four coordinated by two bromine atoms and two N atoms from different tib ligands, the other is six coordinated by two chloride atoms and four N atoms from different tib ligands. The thermal gravimetric analysis of complexes 1 and 2 are depicted in the paper. 展开更多
