#tesseract

2 posts2 participants0 posts today

A pauta de hoje do #TerSoftware é sobre "gestão de papel". Recentemente, testei OCR para digitalização de tabelas e... não fiquei muito feliz com o resultado.

Acredito que #OCR funcione melhor quando fica bem amarrado com o documento digitalizado (por exemplo, tornando um arquivo PDF buscável), mas para extração de texto, ainda é um grande "depende".

Na minha curta jornada, testei #Tesseract e #Docling. Talvez funcione com código bem escrito, mas acabei me rendendo e indo "no muque" mesmo.

O Tesseract parece bem fácil de instalar no Linux (mesmo no #openSUSE Leap, que tem suas limitações por sair do SUSE empresarial, achei fácil), mas o Docling exigiu alguns malabarismos com ambientes em Python (usando conda e pip).

Para texto corrido, o Tesseract parece bem suficiente, já. Pode ser rodado via linha de comando e, pelo menos no openSUSE Leap, vários dicionários se encontram empacotados para facilitar.

Tonight I had the opportunity to attend the live performance of #Tesseract at the #RessurectionFest. I have known their music for years, but was in the least preapared for this incredible show. True bearers of the #ProgressiveRock ethos.

This concert felt like being in the driver's seat of a fast, loud race car. Scary, but enthralling. No clue where it is exactly taking you, but for sure into interesting places.

Vildhjarta – Där skogen sjunger under evighetens granar Review

By Dear Hollow

You could make the case that Vildhjarta’s third full-length is too late to be relevant. There are few that djent as hard as the Swedes, and their own influence exists in pockets of tone-abusing youngsters and diehard veterans who just keep releasing shit: Tesseract, Periphery, and Animals As Leaders, for example. I’ve always thought that Vildhjarta is the more curious Humanity’s Last Breath, utilizing a similarly crushingly heavy bone-to-dust djent tone, dark atmosphere, and vocal attack,1 but with a shimmering ethereality more akin to Uneven Structure or older The Contortionist, heaven and hell alike. Regardless, you can bet your bottom dollar that Vildhjarta djents. Hard.

Vildhjarta has a fervent fanbase in spite of having relatively little music to speak of. Having coined the mysterious “thall!” battle cry and influencing a ton of “djentlemen,” Där skogen sjunger under evighetens granar is only their third full-length. The influential concept album Måsstaden was a landmark of djenty deathcore, but was immediately left almost entirely unanswered (apart from the Thousands of Evils EP in 2013) until 2021 with the release of Måsstaden under vatten (“seagull city underwater”). That album rekindled what made the act so formidable to begin with: downtuned choppy djent riffs, reverb-laden leads that sway between dissonant and hyper-melodic, and staccato overlapping rhythms. Där skogen sjunger under evighetens granar is undeniably Vildhjarta in this way, although it benefits from its more playful approach, streamlined songwriting, heightened atmosphere, and deepened weight, but it won’t change your mind about Vildhjarta in its one-note and overlong glory.

Vildhjarta has always been unique for its ability to take the novelty and highlights of djent and make an experience out of it. Där skogen sjunger under evighetens granar is the most pristine and positive of the band’s discography, reflecting its sanguine title,2 compared to the ominous ambiance pervading the dark fairytales of the Måsstaden suite. While its predecessors dove headfirst into the darkness, Där skogen... seems to embrace a more dreamy attitude reminiscent of post-rock bands like Sigur Rós or Hammock. Yes, the Swedes have amped the density and weight of their djent, but have also raised its hell-gazing heads to the cosmos. There are certainly moments of ominous dissonance (“Där mossan möter havet”), but most tracks feel downright cheery by comparison. Toss in some well-placed vocals that range from dreamy to powerful (“Sargasso,” “Där mossan möter havet,” “Kristallfågel,” “? regnet, the ?,” “Viktlös & evig”), and stargazing to djent never seemed so apt.

That being said, if drop-tuned djenty beatdowns interspersed with reverb-y leads, wild runs, and synth overlays are not your thing, that’s basically what Vildhjarta does for fifty-six minutes straight, which is downright brief compared to its predecessor’s eighty-one minutes. One riff to rule them all: variety and differentiation are not names of the game for Vildhjarta. Even tempo remains at a comfortable 90 bpm for the majority of the album; sudden blastbeats give the illusion of speed. Vilhelm Bladin’s harsh vocals remain predictable death growls with a climax of a shriek here and there aside from sparse, almost-spoken word (“Hösten som togs ifrån mig,” “Den spanska känslan”), although the cleans have much more range. Guitar work remains entirely predictable, aside from the pairing of melancholy plucking and its punchy polyrhythm call-back (“Viktlös & evig”) or some almost classical noodling (“Den spanska känslan”).

Yes, Vildhjarta is an experience of surreal proportions, particularly compared to the legions of their super-serious genremates. Där skogen sjunger under evighetens granar’s pristine atmosphere stands out among even its own shadowy discography, although it retains all the act’s trademarks. The act works better as a trio, as it forces them to cut the fluff into what works and what doesn’t. That being said, it does not justify why you should spend nearly an hour getting a djent concussion only to gaze up at the stars through newly encephalopathic eyes. Old habits die hard, and while mysterious and enigmatic, the Swedes’ formula is predictable, if not hella fun for the initiated. Ultimately, if you’re a fan, Vildhjarta is above-average djent; if you’re not a fan, Vildhjarta is average djent.

Continued thread

Then I was asked for #berkeley, and this was the first real inflection point for the project.

Berkeley didn't use Legistar. It didn't use any system I had seen before, and it had minutes going back to 1905.

This was going to be prohibitively expensive using AWS' OCR tool, so I had to get creative.

This was where I started exploring #tesseract, and building a pipeline for this project that could run entirely on one machine.

@inkorrupt Ich habe munkeln hören, dass gerade ein paar Leute daran sitzen, aber der Vorgang zieht sich ganz schön hin. Ist ja auch ein ordentlicher Batzen schlechter Scans. #Tesseract muss ganz schön durchatmen. Wenn das Ergebnis brauchbar ist, werden vermutlich noch eine Menge Fehler drin sein. Aber das wäre immer noch besser als gar keine Suchmöglichkeit.
