Fo' de land sakes, Massa Dick, wot am dat contraption yo' boys dun put togedder back ob de bahn yesterday? "Why, Aleck, don't you know what that is?" returned Dick Rover, with a smile at the colored man. "That's a biplane." "A biplane, eh?" repeated Alexander Pop, the colored helper around the Rover homestead. He scratched his woolly head thoughtfully. "Yo' don't mean to say it am lak a plane a carpenter man uses, does yo', Massa Dick? 'Pears lak to me it was moah lak some ship sails layin' down, -somethin' lak dem ships we see over in Africy, when we went into dem jungles to find yo' fadder.
Six feet water in the hold, sir! That would not have been a pleasant announcement to the captain of the 'Aurora' at any time, but its unpleasantness was vastly increased by the fact that it greeted him near the termination of what had been, up to that point of time, an exceedingly prosperous voyage. "Are you sure, Davis?" asked the captain; "try again." He gave the order under the influence of that feeling which is styled "hoping against hope," and himself accompanied the ship's carpenter to see it obeyed. "Six feet two inches," was the result of this investigation. The vessel, a large English brig, had sprung a leak, and was rolling heavily in a somewhat rough sea off the east coast of Africa.
Dick, do you notice how the wind is freshening? "Yes, Sam, I've been watching it for ten minutes. I think we are in for a storm." "Exactly my idea, and I shouldn't be surprised if it proved a heavy one, too. How far are we from shore?" "Not over three miles, to my reckoning." "Perhaps we had better turn back," and Sam Rover, the youngest of the three Rover brothers, shook his head doubtfully. "Oh, I reckon we'll be safe enough," responded Dick Rover, who was several years older. "I know more about sailing a yacht than I did when we followed up the Baxters on the Atlantic Ocean.
In the current age of information technology, the issues of distributing and utilizing images efficiently and effectively are of substantial concern. Solutions to many of the problems arising from these issues are provided by techniques of image processing, among which segmentation and compression are topics of this book. Image segmentation is a process for dividing an image into its constituent parts. For block-based segmentation using statistical classification, an image is divided into blocks and a feature vector is formed for each block by grouping statistics of its pixel intensities. Conventional block-based segmentation algorithms classify each block separately, assuming independence of feature vectors. Image Segmentation and Compression Using Hidden Markov Models presents a new algorithm that models the statistical dependence among image blocks by two dimensional hidden Markov models (HMMs). Formulas for estimating the model according to the maximum likelihood criterion are derived from the EM algorithm. To segment an image, optimal classes are searched jointly for all the blocks by the maximum a posteriori (MAP) rule. The 2-D HMM is extended to multiresolution so that more context information is exploited in classification and fast progressive segmentation schemes can be formed naturally. The second issue addressed in the book is the design of joint compression and classification systems using the 2-D HMM and vector quantization. A classifier designed with the side goal of good compression often outperforms one aimed solely at classification because overfitting to training data is suppressed by vector quantization. Image Segmentation and Compression Using Hidden Markov Models is an essential reference source for researchers and engineers working in statistical signal processing or image processing, especially those who are interested in hidden Markov models. It is also of value to those working on statistical modeling.
In God's Empire, Hilary M. Carey charts Britain's nineteenth-century transformation from Protestant nation to free Christian empire through the history of the colonial missionary movement. This wide-ranging reassessment of the religious character of the second British empire provides a clear account of the promotional strategies of the major churches and church parties which worked to plant settler Christianity in British domains. Based on extensive use of original archival and rare published sources, the author explores major debates such as the relationship between religion and colonization, church-state relations, Irish Catholics in the empire, the impact of the Scottish Disruption on colonial Presbyterianism, competition between Evangelicals and other Anglicans in the colonies, and between British and American strands of Methodism in British North America.
