Cursive script recognition using wildcards and multiple experts

Variability in handwriting styles suggests that many letter recognition engines cannot correctly identify some hand-written letters of poor quality at reasonable computational cost. Methods that are capable of searching the resulting sparse graph of letter candidates are therefore required. The method presented here employs ‘wildcards’ to represent missing letter candidates. Multiple experts are used to represent different aspects of handwriting. Each expert evaluates closeness of match and indicates its confidence. Explanation experts determine the degree to which the word alternative under consideration explains extraneous letter candidates. Schemata for normalisation and combination of scores are investigated and their performance compared. Hill climbing yields near-optimal combination weights that outperform comparable methods on identical dynamic handwriting data

Sustainable suburbs : the developer’s challenge

As our cities expand, developers are transforming more and more land to create our suburbs of the future. Developers and government bodies have a golden opportunity to design suburbs that are not only great places to live, but also are environmentally sensitive and sustainable. This is a unique opportunity, as significant changes after development are constrained by the configuration of the subdivision, and then by the construction of the dwellings. This paper explores some of these issues by presenting initial findings from the CRCCI, Sustainable Subdivisions Project. The Project examines the drivers and barriers that land developers face when trying to achieve sustainable subdivisions. This paper will review the results from a series of industry interviews and workshops and explore possible ways forward. In addition, the possible effect on the way future land subdivision is managed and planned as a result of recent changes in the energy efficiency provisions of the Building Code of Australia will be explored. This paper highlights problems that both builders and land developers may face through poor subdivision design. Finally an innovative program being driven by a major land developer will be introduced. The program aims to deliver over 400 energy and water efficient homes through a series of compulsory and voluntary schemes that the developer is designing, funding and implementing. This program is the first large-scale development in Australia that demonstrates how developers can help achieve environmentally sensitive and sustainable suburbs of the future

Property\u27s Morale

A foundational argument long invoked to justify stable property rights is that property law must protect settled expectations. Respect for expectations unites otherwise disparate strands of property theory focused on ex ante incentives, individual identity, and community. It also privileges resistance to legal transitions that transgress reliance interests. When changes in law unsettle expectations, such changes are thought to generate disincentives that Frank Michelman famously labeled demoralization costs. Although rarely approached in these terms, arguments for legal certainty reflect underlying psychological assumptions about how people contemplate property rights when choosing whether and how to work, invest, create, bolster identity, join a community, and make other decisions at property’s core. More precisely, demoralization is predicated on a kind of paralysis flowing from anxieties about instability, unfair singling out, and majoritarian expropriation that can be sparked in legal transitions. This prevailing psychological portrait of expectations has considerable intuitive appeal and is widely influential. It is, however, distinctly incomplete. This Article offers an alternative picture of the expectations with which people approach property and the corresponding anxieties that might cause people to hesitate. From this perspective, stability is less important than assurances that the legal system will respond when external forces threaten to overwhelm the value owners create, that it will provide a fair process of adjustment over time, and that it will ensure inclusion. In short, property law can offer morale benefits that are every bit as critical as demoralization costs. Property theory and doctrine often juxtapose ex ante certainty against ex post flexibility; however, a morale lens underscores that legal transitions can signal responsiveness as easily as instability. Doctrinally, this understanding recalibrates property law’s approach to expectation. Normatively, property’s largely ignored, but absolutely vital, morale function provides a framework for understanding how the legal system can buoy confidence in greater balance, fostering all of the work with which property is so rightly associated

Recognition of handwritten music scores

The recognition of handwritten music scores still remains an open problem. The existing approaches can only deal with very simple handwritten scores mainly because of the variability in the handwriting style and the variability in the composition of groups of music notes (i.e. compound music notes). In this work on the one hand I study the isolated symbols (i.e half-note, quarter-note, clefs, sharps) and on the other hand the compound music notes. Firstly, I will separate the isolated symbols (i.e half-notes, quarter-notes, clefs, sharps) to the compounds and I will study each one separately. The isolated symbols will be recognized with symbol recognition methods and compounds with a primitive hierarchy and syntactic rules. The method has been tested using several handwritten music scores of the CVC-MUSCIMA database and compared with a commercial Optical Music Recognition software. Given that my method is learning-free, the obtained results are promising.El reconeixement de partitures musicals manuscrites segueix sent un problema obert. Els enfocaments existents només poden reconéixer partitures manuscrites molt simples, principalment a causa de la variabilitat en l'estil d'escriptura i la variabilitat en la composició dels grups de notes musicals (p.e. els símbols musicals compostos). En aquest treball, per començar, se separaran els símbols simples (p.e blanques, negres, claus, sostinguts) dels compostos i els estudiaré per separat. Els símbols simples mitjançant mètodes de reconeixement de símbols i els compostos a partir d'una jerarquia de primitives i regles sintàctiques.
