At Mount Cook

As we'd done most of the walks before and we were feeling quite tired, we limited our exertions on what was a warm sunny day. In the morning we went to the Tasman Glacier and Lake. The walk takes you up the moraine wall to a viewpoint overlooking the lake and back to the glacier.…

Birds

We are trying to take some pictures of birds on this trip. Not many so far but we will try to add some as we go along. Gulls flying Goldfinch near Allan's Beach Diver taking off at Raumati Beach Diver at Mercury Bay Little Stint on Cooks Beach Silvereyes Gull at Mercury Bay Gulls at…

Christchurch

This is a bit out of order as we did this before we drove south to Dunedin. Flew into Christchurch from Sydney across the South Island mountains in an ESE direction, just as dusk was descending. Visibility was good and Mount Cook stood majestically in the evening sun with the glacial lake Pukako clearly visible…

En route from Dunedin to Mount Cook

We went from Dunedin via Middlemarch (not quite straight out of a Victorian novel - someone with a sense of humour?) and had a lovely coffee stop at the Kissing Gate Cafe. Coffee - something the NZers do so well. Middlemarch is also on the Central Otago Rail Trail, an excellent cycle trail following the…

Allan’s Beach – Otago Peninsula

The reason we came here. We were the only ones there. Possibly one of the most beautiful beaches in the world. The tide was out exposing acres of firm pristine grey/white sand. There were several sea lions on the beach and a new one would arrive every so often. The kelp thrown up by the…

Image-walking

It is easy to underestimate the process of isolating the glyphs within a document. To start with, the possible variety of documents that can be presented for transcription is enormous. They can be dark, smudged, torn, with or without a border, straight or crooked, rows can be sloping or straight, writing can slope to the…

Getting to a Trained Model

As mentioned previously, in order to train the model you need to identify the shapes (characters) that you need to use. Essentially you are trying to deconstruct a document into its constituent character shapes and then to attach the meaning of those shapes. The result should be that if you have identified a sufficiently representative sample of…

Training and Transcribing

The choice of Machine Learning (ML) as the recognition method necessitates a specific approach to the recognition problem. 'Learning' refers to the computer ML model being provided with a set of examples and their meanings such that when later the model is presented with new examples, it can successfully interpret those examples and ascribe the correct meaning to…

Document vs. an Image of a Document

It may be obvious to many but it will not be so obvious to many more. When you look at a scanned or photographed image of a document on a computer screen you see pretty much the same as when you look at the original document and we have no trouble reading it assuming the…
